gnu_get_libc_version, gnu_get_libc_release \- get glibc version and release
.SH SYNOPSIS
.nf
.B #include <gnu/libc-version.h>

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

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

The function
.BR 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

.SH CONFORMING TO
These functions are glibc-specific.
.SH EXAMPLE
When run, the program below will produce output such as the following:
.in +4n
.nf

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