getgid, getegid — get group identity
#include <unistd.h> #include <sys/types.h>

getgid() returns the real
group ID of the calling process.
getegid() returns the
effective group ID of the calling process.
The original Linux getgid()
and getegid() system calls
supported only 16-bit group IDs. Subsequently, Linux 2.4
added getgid32() and
getegid32(), supporting 32-bit
IDs. The glibc getgid() and
getegid() wrapper functions
transparently deal with the variations across kernel
versions.
