getresuid, getresgid − get real, effective and saved user/group IDs
#define
_GNU_SOURCE
#include <unistd.h>
int
getresuid(uid_t *ruid, uid_t
*euid, uid_t *suid);
int getresgid(gid_t *rgid, gid_t
*egid, gid_t *sgid);
getresuid() returns the real UID, the effective UID, and the saved set-user-ID of the calling process, in the arguments ruid, euid, and suid, respectively. getresgid() performs the analogous task for the process’s group IDs.
On success, zero is returned. On error, −1 is returned, and errno is set appropriately.

One of the arguments specified an address outside the calling program’s address space. |
These system calls appeared on Linux starting with kernel 2.1.44.
The prototypes are given by glibc since version 2.3.2, provided _GNU_SOURCE is defined.
These calls are nonstandard; they also appear on HP-UX and some of the BSDs.
