Become an FSF associate member by January It was launched in by Richard Stallman rms and has been developed by many people working together for the sake of freedom of all software users to control their computing. Technically, GNU is generally like Unix. But unlike Unix, GNU gives its users freedom. Also, the GNU system is not a single static set of programs; users and distributors may select different packages according to their needs and desires.

The result is still a variant of the GNU system. See the video explanation. Free software means the users have the freedom to run, copy, distribute, study, change and improve the software. Free software is a matter of liberty, not price. More precisely, free software means users of a program have the four essential freedoms :. Developments in technology and network use have made these freedoms even more important now than they were in Nowadays the free software movement goes far beyond developing the GNU system.

See the Free Software Foundation's web site for more about what we do, and a list of ways you can help. GNU is a Unix-like operating system. That means it is a collection of many programs: applications, libraries, developer tools, even games. GNU is typically used with a kernel called Linux.

Volunteers continue developing the Hurd because it is an interesting technical project. This year, choose Freedom as a gift. Connect and share knowledge within a single location that is structured and easy to search.

I know it is a Macro we are passing to a function. How do you explain what is the use of this macro, and in which scenario i have to use this?.

If you use an altered functionality of a portable function, I can't think of an example but I believe they do exist, it may create subtle bugs in non-GNU platforms.

Some functions not mandated by the standard are provided in libraries, but are only available when some feature test macro is defined. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

If you decompress the zip file using a command-line tool, you can use a command-line option to automatically overwrite the file, for example by using the -y command-line option with 7zip.
