To get GNU libc version in C language at run-time, you can call gnu_get_libc_version() and gnu_get_libc_release().
- gnu_get_libc_version() returns string that identifies the glibc version available on the system.
- gnu_get_libc_release() returns string indicates the release status of the glibc version available on the system.
And, you can retrieve _CS_GNU_LIBC_VERSION with confstr().
Here is example, test_version.c:
#include <stdio.h>
#include <gnu/libc-version.h>
#include <stdlib.h>
#include <unistd.h>
main(){
printf("GNU libc version: %s\n", gnu_get_libc_version());
printf("GNU libc release: %s\n", gnu_get_libc_release());
char *buf; size_t n;
n = confstr(_CS_GNU_LIBC_VERSION, NULL, (size_t)0);
if ((buf = malloc(n)) == NULL)
abort();
confstr(_CS_GNU_LIBC_VERSION, buf, n);
printf("_CS_GNU_LIBC_VERSION: %s\n", buf );
free( buf );
}
