GNU_GET_LIBC_VERSION(3) Linux Programmer's ManualGNU_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). ┌──────────────────────────────────────┬───────────────┬─────────┐ │Interface │ Attribute │ Value │ ├──────────────────────────────────────┼───────────────┼─────────┤ │gnu_get_libc_version(), │ Thread safety │ MT-Safe │ │gnu_get_libc_release() │ │ │ └──────────────────────────────────────┴───────────────┴─────────┘
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 Program source #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); }
