getgid2
Get group identity
Usage
#include <unistd.h>
gid_t getgid(void); gid_t getegid(void);
Library
Standard C library (libc, -lc)
Overview
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 and never modify errno.
Versions
On Alpha, instead of a pair of getgid() and getegid() system calls, a single getxgid() system call is provided, which returns a pair of real and effective GIDs. The glibc getgid() and getegid() wrapper functions transparently deal with this. See syscall(2) for details regarding register mapping.
