gnu_get_libc_version(3) Library Functions Manual gnu_get_libc_version(3) NAME gnu_get_libc_version, gnu_get_libc_release - get glibc version and re- lease LIBRARY Standard C library (libc, -lc) SYNOPSIS #include <gnu/libc-version.h> const char *gnu_get_libc_version(void); const char *gnu_get_libc_release(void); DESCRIPTION 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 re- lease status of the glibc version available on the system. This will be a string such as stable. VERSIONS These functions first appeared in glibc 2.1.
