SYNOPSIS

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

uid_t getuid(void);

uid_t geteuid(void);

gid_t getgid(void);

gid_t getegid(void);

DESCRIPTION

The getuid() function returns the real user ID of the calling process. The real user ID identifies the person who is logged in.

The geteuid() function returns the effective user ID of the calling process. The effective user ID gives the process various permissions during execution of "set-user-ID" mode processes which use getuid() to determine the real user ID of the process that invoked them.

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

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