- GNU LESSER GENERAL PUBLIC LICENSE
- Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
- 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL. It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
- This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it. You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations
-below.
-
- When we speak of free software, we are referring to freedom of use,
-not price. Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
- To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights. These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
- For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you. You must make sure that they, too, receive or can get the source
-code. If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it. And you must show them these terms so they know their rights.
-
- We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
- To protect each distributor, we want to make it very clear that
-there is no warranty for the free library. Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-\f
- Finally, software patents pose a constant threat to the existence of
-any free program. We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder. Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
- Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License. This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License. We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
- When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library. The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom. The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
- We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License. It also provides other free software developers Less
-of an advantage over competing non-free programs. These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries. However, the Lesser license provides advantages in certain
-special circumstances.
-
- For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it
-becomes a de-facto standard. To achieve this, non-free programs must
-be allowed to use the library. A more frequent case is that a free
-library does the same job as widely used non-free libraries. In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
- In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software. For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
- Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
- The precise terms and conditions for copying, distribution and
-modification follow. Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library". The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-\f
- GNU LESSER GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
- A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
- The "Library", below, refers to any such software library or work
-which has been distributed under these terms. A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language. (Hereinafter, translation is
-included without limitation in the term "modification".)
-
- "Source code" for a work means the preferred form of the work for
-making modifications to it. For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control
-compilation and installation of the library.
-
- Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it). Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
- 1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
- You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-\f
- 2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) The modified work must itself be a software library.
-
- b) You must cause the files modified to carry prominent notices
- stating that you changed the files and the date of any change.
-
- c) You must cause the whole of the work to be licensed at no
- charge to all third parties under the terms of this License.
-
- d) If a facility in the modified Library refers to a function or a
- table of data to be supplied by an application program that uses
- the facility, other than as an argument passed when the facility
- is invoked, then you must make a good faith effort to ensure that,
- in the event an application does not supply such function or
- table, the facility still operates, and performs whatever part of
- its purpose remains meaningful.
-
- (For example, a function in a library to compute square roots has
- a purpose that is entirely well-defined independent of the
- application. Therefore, Subsection 2d requires that any
- application-supplied function or table used by this function must
- be optional: if the application does not supply it, the square
- root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library. To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License. (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.) Do not make any other change in
-these notices.
-\f
- Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
- This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
- 4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
- If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library". Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
- However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library". The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
- When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library. The
-threshold for this to be true is not precisely defined by law.
-
- If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work. (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
- Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-\f
- 6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
- You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License. You must supply a copy of this License. If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License. Also, you must do one
-of these things:
-
- a) Accompany the work with the complete corresponding
- machine-readable source code for the Library including whatever
- changes were used in the work (which must be distributed under
- Sections 1 and 2 above); and, if the work is an executable linked
- with the Library, with the complete machine-readable "work that
- uses the Library", as object code and/or source code, so that the
- user can modify the Library and then relink to produce a modified
- executable containing the modified Library. (It is understood
- that the user who changes the contents of definitions files in the
- Library will not necessarily be able to recompile the application
- to use the modified definitions.)
-
- b) Use a suitable shared library mechanism for linking with the
- Library. A suitable mechanism is one that (1) uses at run time a
- copy of the library already present on the user's computer system,
- rather than copying library functions into the executable, and (2)
- will operate properly with a modified version of the library, if
- the user installs one, as long as the modified version is
- interface-compatible with the version that the work was made with.
-
- c) Accompany the work with a written offer, valid for at least
- three years, to give the same user the materials specified in
- Subsection 6a, above, for a charge no more than the cost of
- performing this distribution.
-
- d) If distribution of the work is made by offering access to copy
- from a designated place, offer equivalent access to copy the above
- specified materials from the same place.
-
- e) Verify that the user has already received a copy of these
- materials or that you have already sent this user a copy.
-
- For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it. However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
- It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system. Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-\f
- 7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
- a) Accompany the combined library with a copy of the same work
- based on the Library, uncombined with any other library
- facilities. This must be distributed under the terms of the
- Sections above.
-
- b) Give prominent notice with the combined library of the fact
- that part of it is a work based on the Library, and explaining
- where to find the accompanying uncombined form of the same work.
-
- 8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License. Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License. However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
- 9. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Library or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
- 10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-\f
- 11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all. For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply, and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License
-may add an explicit geographical distribution limitation excluding those
-countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation. If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-\f
- 14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission. For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this. Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
- NO WARRANTY
-
- 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
- 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.

-\`configure' configures libnl 1.0-pre6 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']

-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --datadir=DIR read-only architecture-independent data [PREFIX/share]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]
- --libdir=DIR object code libraries [EPREFIX/lib]
- --includedir=DIR C header files [PREFIX/include]
- --oldincludedir=DIR C header files for non-gcc [/usr/include]
- --infodir=DIR info documentation [PREFIX/info]

-Optional Features:
- --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
- --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
- --enable-verbose-errors enable verbose errors (debugging)
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have

- * to allow subsystems to have their own formatting rules without the need to
- * make the underlying layer be aware of it. It can also be useful to transfer
- * arrays, lists and flattened trees.

- * @par 1) Creating a new netlink message
- * @code
- * // The most common way to start creating a message is by providing an
- * // defined netlink header to nlmsg_build():
- * struct nlmsghdr hdr = {
- * .nlmsg_type = MY_TYPE,
- * .nlmsg_flags = MY_FLAGS,
- * };
- * struct nl_msg *msg = nlmsg_build(&hdr);
- *
- * // For simple usages where only the message type and flags is of
- * // interenst a shortcut can be taken:
- * struct nl_msg *msg = nlmsg_build_simple(MY_TYPE, MY_FLAGS);
- *
- * // When using a headerless message for creating nested attributes
- * // the header is not required and nlmsg_build_no_hdr() may be used:
- * struct nl_msg *msg = nlmsg_build_no_hdr();
- *
- * // The header can later be retrieved with nlmsg_hdr() and changed again:
- * nlmsg_hdr(msg)->nlmsg_flags |= YET_ANOTHER_FLAG;
- * @endcode
- *
- * @par 2) Appending data to the message
- * @code
- * // Payload may be added to the message via nlmsg_append(). The fourth
- * // parameter specifies whether to pad up to NLMSG_ALIGN to make sure
- * // that a possible further data block is properly aligned.
- * nlmsg_append(msg, &mydata, sizeof(mydata), 0);
- * @endcode
- *
- * @par 3) Cleaning up message construction
- * @code
- * // After successful use of the message, the memory must be freed
- * // using nlmsg_free()
- * nlmsg_free(msg);
- * @endcode
- *
- * @par Example 2 (Parsing messages):
- * @code
- * int n;
- * unsigned char *buf;
- * struct nlmsghdr *hdr;
- *
- * n = nl_recv(handle, NULL, &buf);
- *
- * hdr = (struct nlmsghdr *) buf;
- * while (nlmsg_ok(hdr, n)) {
- * // Process message here...
- * hdr = nlmsg_next(hdr, &n);

- * @par 1) Creating the netlink handle
- * @code

- * // Allocate and initialize a new netlink handle
- * handle = nl_handle_new();
- *
- * // Are multiple handles being allocated? You have to provide a unique
- * // netlink process id and overwrite the default local process id.
- * nl_handle_set_pid(handle, MY_UNIQUE_PID);
- *
- * // Is this socket used for event processing? You need to disable sequence
- * // number checking in order to be able to receive messages not explicitely
- * // requested.
- * nl_disable_sequence_check(handle);
- *
- * // Use nl_handle_get_fd() to fetch the file description, for example to
- * // put a socket into non-blocking i/o mode.
- * fcntl(nl_handle_get_fd(handle), F_SETFL, O_NONBLOCK);
- * @endcode
- *
- * @par 2) Joining Groups
- * @code
- * // You may join/subscribe to as many groups as you want, don't forget
- * // to eventually disable sequence number checking. Note: Joining must
- * // be done before connecting/binding the socket.
- * nl_join_groups(handle, GROUP_ID1 | GROUP_ID2);
- * @endcode
- *
- * @par 3) Connecting the socket
- * @code
- * // Bind and connect the socket to a protocol, NETLINK_ROUTE in this example.
- * nl_connect(handle, NETLINK_ROUTE);
- * @endcode
- *
- * @par 4) Sending data
- * @code
- * // The most rudimentary method is to use nl_sendto() simply pushing
- * // a piece of data to the other netlink peer. This method is not
- * // recommended.
- * const char buf[] = { 0x01, 0x02, 0x03, 0x04 };
- * nl_sendto(handle, buf, sizeof(buf));
- *
- * // A more comfortable interface is nl_send() taking a pointer to
- * // a netlink message.
- * struct nl_msg *msg = my_msg_builder();
- * nl_send(handle, nlmsg_hdr(msg));
- *
- * // nl_sendmsg() provides additional control over the sendmsg() message
- * // header in order to allow more specific addressing of multiple peers etc.
- * struct msghdr hdr = { ... };
- * nl_sendmsg(handle, nlmsg_hdr(msg), &hdr);
- *
- * // You're probably too lazy to fill out the netlink pid, sequence number
- * // and message flags all the time. nl_send_auto_complete() automatically
- * // extends your message header as needed with an appropriate sequence
- * // number, the netlink pid stored in the netlink handle and the message
- * // flags NLM_F_REQUEST and NLM_F_ACK
- * nl_send_auto_complete(handle, nlmsg_hdr(msg));
- *
- * // Simple protocols don't require the complex message construction interface
- * // and may favour nl_send_simple() to easly send a bunch of payload
- * // encapsulated in a netlink message header.
- * nl_send_simple(handle, MY_MSG_TYPE, 0, buf, sizeof(buf));
- * @endcode
- *
- * @par 5) Receiving data
- * @code
- * // nl_recv() receives a single message allocating a buffer for the message
- * // content and gives back the pointer to you.
- * struct sockaddr_nl peer;
- * unsigned char *msg;
- * nl_recv(handle, &peer, &msg);
- *
- * // nl_recvmsgs() receives a bunch of messages until the callback system
- * // orders it to state, usually after receving a compolete multi part
- * // message series.
- * nl_recvmsgs(handle, my_callback_configuration);
- *
- * // nl_recvmsgs_def() acts just like nl_recvmsg() but uses the callback
- * // configuration stored in the handle.
- * nl_recvmsgs_def(handle);
- *
- * // In case you want to wait for the ACK to be recieved that you requested
- * // with your latest message, you can call nl_wait_for_ack()
- * nl_wait_for_ack(handle);
- * @endcode
- *
- * @par 6) Cleaning up
- * @code
- * // Close the socket first to release kernel memory
- * nl_close(handle);
- *
- * // Finally destroy the netlink handle
- * nl_handle_destroy(handle);

- * IFF_MASTER Used by teql
- * IFF_SLAVE Used by teql
- * IFF_PORTSEL Indicates this link allows port selection
- * IFF_AUTOMEDIA Indicates this link selects port automatically
- * IFF_DYNAMIC Indicates the address of this link is dynamic
- * IFF_RUNNING Link is running and carrier is ok.
- * IFF_NOTRAILERS Unused, BSD compat.
- * @endcode
- *
- * @par Notes on IFF_PROMISC and IFF_ALLMULTI flags
- * Although you can query the status of IFF_PROMISC and IFF_ALLMULTI
- * they do not represent the actual state in the kernel but rather
- * whether the flag has been enabled/disabled by userspace. The link
- * may be in promiscious mode even if IFF_PROMISC is not set in a link
- * dump request response because promiscity might be needed by the driver
- * for a period of time.
- *
- * @par 1) Retrieving information about available links
- * @code
- * // The first step is to retrieve a list of all available interfaces within
- * // the kernel and put them into a cache.
- * struct nl_cache *cache = rtnl_link_alloc_cache(nl_handle);
- *
- * // In a second step, a specific link may be looked up by either interface
- * // index or interface name.
- * struct rtnl_link *link = rtnl_link_get_by_name(cache, "lo");
- *
- * // rtnl_link_get_by_name() is the short version for translating the
- * // interface name to an interface index first like this:
- * int ifindex = rtnl_link_name2i(cache, "lo");
- * struct rtnl_link *link = rtnl_link_get(cache, ifindex);
- *
- * // After successful usage, the object must be given back to the cache
- * rtnl_link_put(link);
- * @endcode
- *
- * @par 2) Changing link attributes
- * @code
- * // In order to change any attributes of an existing link, we must allocate
- * // a new link to hold the change requests:
- * struct rtnl_link *request = rtnl_link_alloc();
- *
- * // Now we can go on and specify the attributes we want to change:
- * rtnl_link_set_weight(request, 300);
- * rtnl_link_set_mtu(request, 1360);
- *
- * // We can also shut an interface down administratively
- * rtnl_link_unset_flags(request, rtnl_link_str2flags("up"));
- *
- * // Actually, we should know which link to change, so let's look it up
- * struct rtnl_link *old = rtnl_link_get(cache, "eth0");
- *
- * // Two ways exist to commit this change request, the first one is to
- * // build the required netlink message and send it out in one single
- * // step:
- * rtnl_link_change(nl_handle, old, request);
- *
- * // An alternative way is to build the netlink message and send it
- * // out yourself using nl_send_auto_complete()
- * struct nl_msg *msg = rtnl_link_build_change_request(old, request);
- * nl_send_auto_complete(nl_handle, nlmsg_hdr(msg));
- * nlmsg_free(msg);
- *
- * // Don't forget to give back the link object ;->
- * rtnl_link_put(old);
- * @endcode
- * @{

-/**
- * @ingroup rtnl
- * @defgroup neigh Neighbours
- * @brief
- *
- * The neighbour table establishes bindings between protocol addresses and
- * link layer addresses for hosts sharing the same physical link. This
- * module allows you to access and manipulate the content of these tables.
- *
- * @par Neighbour States
- * @code
- * NUD_INCOMPLETE
- * NUD_REACHABLE
- * NUD_STALE
- * NUD_DELAY
- * NUD_PROBE
- * NUD_FAILED
- * NUD_NOARP
- * NUD_PERMANENT
- * @endcode
- *
- * @par Neighbour Flags
- * @code
- * NTF_PROXY
- * NTF_ROUTER
- * @endcode
- *
- * @par Neighbour Identification
- * A neighbour is uniquely identified by the attributes listed below, whenever
- * you refer to an existing neighbour all of the attributes must be set.
- * Neighbours from caches automatically have all required attributes set.
- * - interface index (rtnl_neigh_set_ifindex())
- * - destination address (rtnl_neigh_set_dst())
- *
- * @par Changeable Attributes
- * \anchor neigh_changeable
- * - state (rtnl_neigh_set_state())
- * - link layer address (rtnl_neigh_set_lladdr())
- *
- * @par Required Caches for Dumping
- * In order to dump neighbour attributes you must provide the following
- * caches via nl_cache_provide()
- * - link cache holding all links
- *
- * @par TODO
- * - Document proxy settings
- * - Document states and their influence
- *
- * @par 1) Retrieving information about configured neighbours
- * @code
- * // The first step is to retrieve a list of all available neighbour within
- * // the kernel and put them into a cache.
- * struct nl_cache *cache = rtnl_neigh_alloc_cache(handle);
- *
- * // Neighbours can then be looked up by the interface and destination
- * // address:
- * struct rtnl_neigh *neigh = rtnl_neigh_get(cache, ifindex, dst_addr);
- *
- * // After successful usage, the object must be given back to the cache
- * rtnl_neigh_put(neigh);
- * @endcode
- *
- * @par 2) Adding new neighbours
- * @code
- * // Allocate an empty neighbour handle to be filled out with the attributes
- * // of the new neighbour.
- * struct rtnl_neigh *neigh = rtnl_neigh_alloc();
- *
- * // Fill out the attributes of the new neighbour
- * rtnl_neigh_set_ifindex(neigh, ifindex);
- * rtnl_neigh_set_dst(neigh, dst_addr);
- * rtnl_neigh_set_state(neigh, rtnl_neigh_str2state("permanent"));
- *
- * // Build the netlink message and send it to the kernel, the operation will
- * // block until the operation has been completed. Alternatively the required
- * // netlink message can be built using rtnl_neigh_build_add_request()
- * // to be sent out using nl_send_auto_complete().
- * rtnl_neigh_add(nl_handle, neigh, NLM_F_REPLACE);
- *
- * // Free the memory
- * rtnl_neigh_put(neigh);
- * @endcode
- *
- * @par 3) Deleting an existing neighbour
- * @code
- * // Allocate an empty neighbour object to be filled out with the attributes
- * // matching the neighbour to be deleted. Alternatively a fully equipped
- * // neighbour object out of a cache can be used instead.
- * struct rtnl_neigh *neigh = rtnl_neigh_alloc();
- *
- * // Neighbours are uniquely identified by their interface index and
- * // destination address, you may fill out other attributes but they
- * // will have no influence.
- * rtnl_neigh_set_ifindex(neigh, ifindex);
- * rtnl_neigh_set_dst(neigh, dst_addr);
- *
- * // Build the netlink message and send it to the kernel, the operation will
- * // block until the operation has been completed. Alternatively the required
- * // netlink message can be built using rtnl_neigh_build_delete_request()
- * // to be sent out using nl_send_auto_complete().
- * rtnl_neigh_delete(handle, neigh, 0);
- *
- * // Free the memory
- * rtnl_neigh_put(neigh);
- * @endcode
- *
- * @par 4) Changing neighbour attributes
- * @code
- * // Allocate an empty neighbour object to be filled out with the attributes
- * // matching the neighbour to be changed and the new parameters. Alternatively
- * // a fully equipped modified neighbour object out of a cache can be used.
- * struct rtnl_neigh *neigh = rtnl_neigh_alloc();
- *
- * // Identify the neighbour to be changed by its interface index and
- * // destination address
- * rtnl_neigh_set_ifindex(neigh, ifindex);
- * rtnl_neigh_set_dst(neigh, dst_addr);
- *
- * // The link layer address may be modified, if so it is wise to change
- * // its state to "permanent" in order to avoid having it overwritten.
- * rtnl_neigh_set_lladdr(neigh, lladdr);
- *
- * // Secondly the state can be modified allowing normal neighbours to be
- * // converted into permanent entries or to manually confirm a neighbour.
- * rtnl_neigh_set_state(neigh, state);
- *
- * // Build the netlink message and send it to the kernel, the operation will
- * // block until the operation has been completed. Alternatively the required
- * // netlink message can be built using rtnl_neigh_build_change_request()
- * // to be sent out using nl_send_auto_complete().
- * rtnl_neigh_change(handle, neigh, 0);
- *
- * // Free the memory
- * rtnl_neigh_put(neigh);
- * @endcode

-/**
- * @ingroup tc
- * @defgroup qdisc Queueing Disciplines
- *
- * @par Qdisc Handles
- * In general, qdiscs are identified by the major part of a traffic control
- * handle (the upper 16 bits). A few special values exist though:
- * - \c TC_H_ROOT: root qdisc (directly attached to the device)
- * - \c TC_H_INGRESS: ingress qdisc (directly attached to the device)
- * - \c TC_H_UNSPEC: unspecified qdisc (no reference)
- *
- * @par 1) Adding a Qdisc
- * @code
- * // Allocate a new empty qdisc to be filled out
- * struct rtnl_qdisc *qdisc = rtnl_qdisc_alloc();
- *
- * // ... specify the kind of the Qdisc
- * rtnl_qdisc_set_kind(qdisc, "pfifo");
- *
- * // Specify the device the qdisc should be attached to
- * rtnl_qdisc_set_ifindex(qdisc, ifindex);
- *
- * // ... specify the parent qdisc
- * rtnl_qdisc_set_parent(qdisc, TC_H_ROOT);
- *
- * // Specifying the handle is not required but makes reidentifying easier
- * // and may help to avoid adding a qdisc twice.
- * rtnl_qdisc_set_handle(qdisc, 0x000A0000);
- *
- * // Now on to specify the qdisc specific options, see the relevant qdisc
- * // modules for documentation, in this example we set the upper limit of
- * // the packet fifo qdisc to 64
- * rtnl_qdisc_fifo_set_limit(qdisc, 64);
- *
- * rtnl_qdisc_add(handle, qdisc, NLM_R_REPLACE);
- *
- * // Free up the memory
- * rtnl_qdisc_put(qdisc);
- * @endcode
- *
- * @par 2) Deleting a Qdisc
- * @code
- * // Allocate a new empty qdisc to be filled out with the parameters
- * // specifying the qdisc to be deleted. Alternatively a fully equiped
- * // Qdisc object from a cache can be used.
- * struct rtnl_qdisc *qdisc = rtnl_qdisc_alloc();
- *
- * // The interface index of the device the qdisc is on and the parent handle
- * // are the least required fields to be filled out.
- * // Note: Specify TC_H_ROOT or TC_H_INGRESS as parent handle to delete the
- * // root respectively root ingress qdisc.
- * rtnl_qdisc_set_ifindex(qdisc, ifindex);
- * rtnl_qdisc_set_parent(qdisc, parent_handle);
- *
- * // If required for identification, the handle can be specified as well.
- * rtnl_qdisc_set_handle(qdisc, qdisc_handle);
- *
- * // Not required but maybe helpful as sanity check, the kind of the qdisc
- * // can be specified to avoid mistakes.
- * rtnl_qdisc_set_kind(qdisc, "pfifo");
- *
- * // Finally delete the qdisc with rtnl_qdisc_delete(), alternatively
- * // rtnl_qdisc_build_delete_request() can be invoked to generate an
- * // appropritate netlink message to send out.
- * rtnl_qdisc_delete(handle, qdisc);
- *
- * // Free up the memory
- * rtnl_qdisc_put(qdisc);
- * @endcode

- * Allows enqueuing until the currently queued volume in bytes exceeds

- * @par pfifo (Packet FIFO)
- * Allows enquueing until the currently queued number of packets
