    The standard C Library API

    Hello,

    Is the Standard C Library API on the GNU website (http://www.gnu.org/software/libc/man...ode/index.html) the correct reference for all C programmes? Moreover, it is the version of C that is installed on UNIX, Linux and Windows systems by default? What documentation do you use to when coding?

    Regards,

    Dan

    You have to read the footnotes of each function,

    eg
    This function was introduced in Amendment 1 to ISO C90.
    This function is a GNU extension and is declared in string.h.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    You can find the "official reference" of the C (more precisely, of C99 with TC1, TC2 and TC3) standard library here, chapter 7. Note that not all compilers are fully C99 compliant.

    I normally use this website when I need to look for something related to the C standard library.
    I hate real numbers.

    Hi,

    OK, thanks for the pointers. I notices that some functions were labels 'GNU Extensions' so wasn't too sure if I could point general users to that GNU C Library docs, but if they read it clearly I think I can.

    Thanks,

    Dan

    A GNU extention just means that they are standard for the GNU family, and exist beyond the construct of standard C. Usually both gcc and msvc++ both properly comment things that are not standard in their header files.

    If something is a GNU extention that means it will not necessarily exist in other compilers. Make sense?
