* - An absolute path (starting with '/') that gives the exact name of
* the Unix domain socket to listen on.
*
+ * A program that (optionally) daemonizes itself should call this function
+ * *after* daemonization, so that the socket name contains the pid of the
+ * daemon instead of the pid of the program that exited. (Otherwise, "vlogconf
+ * --target <program>.pid" will fail.)
+ *
* Returns 0 if successful, otherwise a positive errno value. If successful,
* sets '*serverp' to the new vlog_server, otherwise to NULL. */
