NAME

getgid, getegid - get group identity  

SYNOPSIS

#include <unistd.h>
#include <sys/types.h>

gid_t getgid(void);
gid_t getegid(void); 

DESCRIPTION

getgid() returns the real group ID of the calling process.

getegid() returns the effective group ID of the calling process.  

ERRORS

These functions are always successful.  

CONFORMING TO

POSIX.1-2001, POSIX.1-2008, 4.3BSD.  

NOTES

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.
