- + GNU LESSER GENERAL PUBLIC LICENSE
- + Version 2.1, February 1999
- +
- + Copyright (C) 1991, 1999 Free Software Foundation, Inc.
- + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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.
- +
- + 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.
- +
- + 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.
- +
- + 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.
- +
- + 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.
- +
- + 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.
- +
- + 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.
- +
- + 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.
- +
- + 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.
- +
- + END OF TERMS AND CONDITIONS
- +
- + How to Apply These Terms to Your New Libraries
- +
- + If you develop a new library, and you want it to be of the greatest
- +possible use to the public, we recommend making it free software that
- +everyone can redistribute and change. You can do so by permitting
- +redistribution under these terms (or, alternatively, under the terms of the
- +ordinary General Public License).
- +
- + To apply these terms, attach the following notices to the library. It is
- +safest to attach them to the start of each source file to most effectively
- +convey the exclusion of warranty; and each file should have at least the
- +"copyright" line and a pointer to where the full notice is found.
- +
- + <one line to give the library's name and a brief idea of what it does.>
- + Copyright (C) <year> <name of author>
- +
- + This library is free software; you can redistribute it and/or
- + modify it under the terms of the GNU Lesser General Public
- + License as published by the Free Software Foundation; either
- + version 2.1 of the License, or (at your option) any later version.
- +
- + This library is distributed in the hope that it will be useful,
- + but WITHOUT ANY WARRANTY; without even the implied warranty of
- + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
- + Lesser General Public License for more details.
- +
- + You should have received a copy of the GNU Lesser General Public
- + License along with this library; if not, write to the Free Software
- + Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- +
- +Also add information on how to contact you by electronic and paper mail.
- +
- +You should also get your employer (if you work as a programmer) or your
- +school, if any, to sign a "copyright disclaimer" for the library, if
- +necessary. Here is a sample; alter the names:
- +
- + Yoyodyne, Inc., hereby disclaims all copyright interest in the
- + library `Frob' (a library for tweaking knobs) written by James Random Hacker.
- +
- + <signature of Ty Coon>, 1 April 1990

- + * g_steal_pointer:
- + * @pp: a pointer to a pointer
- + *
- + * Sets @pp to %NULL, returning the value that was there before.
- + *
- + * Conceptually, this transfers the ownership of the pointer from the
- + * referenced variable to the "caller" of the macro (ie: "steals" the
- + * reference).
- + *
- + * The return value will be properly typed, according to the type of
- + * @pp.
- + *
- + * This can be very useful when combined with g_autoptr() to prevent the
- + * return value of a function from being automatically freed. Consider
- + * the following example (which only works on GCC and clang):
- + *
- + * |[
- + * GObject *
- + * create_object (void)
- + * {
- + * g_autoptr(GObject) obj = g_object_new (G_TYPE_OBJECT, NULL);
- + *
- + * if (early_error_case)
- + * return NULL;
- + *
- + * return g_steal_pointer (&obj);
- + * }
- + * ]|
- + *
- + * It can also be used in similar ways for 'out' parameters and is
- + * particularly useful for dealing with optional out parameters:
- + *
- + * |[
- + * gboolean
- + * get_object (GObject **obj_out)
- + * {
- + * g_autoptr(GObject) obj = g_object_new (G_TYPE_OBJECT, NULL);
- + *
- + * if (early_error_case)
- + * return FALSE;
- + *
- + * if (obj_out)
- + * *obj_out = g_steal_pointer (&obj);
- + *
- + * return TRUE;
- + * }
- + * ]|
- + *
- + * In the above example, the object will be automatically freed in the
- + * early error case and also in the case that %NULL was given for
- + * @obj_out.
- + *
- + * Since: 2.44

- +/**
- + * SECTION:glnxlocalalloc
- + * @title: GLnx local allocation
- + * @short_description: Release local variables automatically when they go out of scope
- + *
- + * These macros leverage the GCC extension __attribute__ ((cleanup))
- + * to allow calling a cleanup function such as g_free() when a
- + * variable goes out of scope. See <ulink
- + * url="http://gcc.gnu.org/onlinedocs/gcc/Variable-Attributes.html">
- + * for more information on the attribute.
- + *
- + * The provided macros make it easy to use the cleanup attribute for
- + * types that come with GLib. The primary two are #glnx_free and
- + * #glnx_unref_object, which correspond to g_free() and
- + * g_object_unref(), respectively.
- + *
- + * The rationale behind this is that particularly when handling error
- + * paths, it can be very tricky to ensure the right variables are
- + * freed. With this, one simply applies glnx_unref_object to a
- + * locally-allocated #GFile for example, and it will be automatically
- + * unreferenced when it goes out of scope.
- + *
- + * Note - you should only use these macros for <emphasis>stack
- + * allocated</emphasis> variables. They don't provide garbage
- + * collection or let you avoid freeing things. They're simply a
- + * compiler assisted deterministic mechanism for calling a cleanup
- + * function when a stack frame ends.
- + *
- + * <example id="gs-lfree"><title>Calling g_free automatically</title>
- + * <programlisting>
- + *
- + * GFile *
- + * create_file (GError **error)
- + * {
- + * glnx_free char *random_id = NULL;
- + *
- + * if (!prepare_file (error))
- + * return NULL;
- + *
- + * random_id = alloc_random_id ();
- + *
- + * return create_file_real (error);
- + * // Note that random_id is freed here automatically
- + * }
- + * </programlisting>
- + * </example>

- +libglnx is the successor to libgsystem: https://git.gnome.org/browse/libgsystem
- +
- +It is for modules which depend on both GLib and Linux, intended to be
- +used as a git submodule.
- +
- +Features:
- +
- + - File APIs which use `openat()` like APIs, but also take a `GCancellable`
- + to support dynamic cancellation
- + - APIs also have a `GError` parameter
- + - High level "shutil", somewhat inspired by Python's
- + - A "console" API for tty output
- + - A backport of the GLib cleanup macros for projects which can't yet take
- + a dependency on 2.40.
- +
- +Why?
- +----
- +
- +There are multiple projects which have a hard dependency on Linux and
- +GLib, such as NetworkManager, ostree, flatpak, etc. It makes sense
- +for them to be able to share Linux-specific APIs.
- +
- +This module also contains some code taken from systemd, which has very
- +high quality LGPLv2+ shared library code, but most of the internal
- +shared library is private, and not namespaced.
- +
- +One could also compare this project to gnulib; the salient differences
- +there are that at least some of this module is eventually destined for
- +inclusion in GLib.
- +
- +Porting from libgsystem
- +-----------------------
- +
- +For all of the filesystem access code, libglnx exposes only
- +fd-relative API, not `GFile*`. It does use `GCancellable` where
- +applicable.
- +
- +For local allocation macros, you should start using the `g_auto`
- +macros from GLib. A backport is included in libglnx. There are a few
- +APIs not defined in GLib yet, such as `glnx_autofd`.
- +
- +`gs_transfer_out_value` is replaced by `g_steal_pointer`.
- +
- +Contributing
- +------------
- +
- +Currently there is not a Bugzilla product - one may be created
- +in the future. You can submit PRs against the Github mirror:
- +
- +https://github.com/GNOME/libglnx/pulls
- +
- +Or alternatively, email one of the maintainers directly.
