gnu_get_libc_version, gnu_get_libc_release - get glibc version and release

#include <gnu/libc-version.h>
const char *gnu_get_libc_version(void);
const char *gnu_get_libc_release(void);

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 release status of the glibc version available on the system. This will be a string such as stable.

These functions first appeared in glibc in version 2.1.

Interface Attribute Value
gnu_get_libc_version (), gnu_get_libc_release () Thread safety MT-Safe

These functions are glibc-specific.

When run, the program below will produce output such as the following:


$ ./a.out
GNU libc version: 2.8
GNU libc release: stable

#include <gnu/libc-version.h>
#include <stdlib.h>
#include <stdio.h>
int
main(int argc, char *argv[])
{
    printf("GNU libc version: %s\n", gnu_get_libc_version());
    printf("GNU libc release: %s\n", gnu_get_libc_release());
    exit(EXIT_SUCCESS);
}
