GNU_GET_LIBC_VERSION(3) Linux Programmer's Manual GNU_GET_LIBC_VERSION(3)
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.
For an explanation of the terms used in this section, see
attributes(7).
