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, 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.
