gnu_get_libc_version(3)    Library Functions Manual    gnu_get_libc_version(3)

NAME
       gnu_get_libc_version,  gnu_get_libc_release - get glibc version and re-
       lease

LIBRARY
       Standard C library (libc, -lc)

SYNOPSIS
       #include <gnu/libc-version.h>

       const char *gnu_get_libc_version(void);
       const char *gnu_get_libc_release(void);

DESCRIPTION
       The function gnu_get_libc_version() returns a  string  that  identifies
       the glibc version available on the system.

       The  function gnu_get_libc_release() returns a string indicates the re-
       lease status of the glibc version available on the system.   This  will
       be a string such as stable.

VERSIONS
       These functions first appeared in glibc 2.1.

           GNU libc version: 2.8
           GNU libc release: stable

   Program source

       #include <stdio.h>
       #include <stdlib.h>

       #include <gnu/libc-version.h>

       int
       main(void)
       {
           printf("GNU libc version: %s\n", gnu_get_libc_version());
           printf("GNU libc release: %s\n", gnu_get_libc_release());
           exit(EXIT_SUCCESS);
       }
