       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.

       int
       main(int argc, char *argv[])
       {
	   printf("GNU libc version: %s
", gnu_get_libc_version());
	   printf("GNU libc release: %s
", gnu_get_libc_release());
	   exit(EXIT_SUCCESS);
