NAME 🖥️ getresgid32 🖥️

get real, effective, and saved user/group IDs

LIBRARY

Standard C library (libc, -lc)

SYNOPSIS

#define _GNU_SOURCE /* See feature_test_macros(7) */
#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);

DESCRIPTION

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.

RETURN VALUE

On success, zero is returned. On error, -1 is returned, and errno is set to indicate the error.

ERRORS

EFAULT
One of the arguments specified an address outside the calling program’s address space.

STANDARDS

None. These calls also appear on HP-UX and some of the BSDs.

HISTORY

Linux 2.1.44, glibc 2.3.2.

The original Linux getresuid() and getresgid() system calls supported only 16-bit user and group IDs. Subsequently, Linux 2.4 added getresuid32() and getresgid32(), supporting 32-bit IDs. The glibc getresuid() and getresgid() wrapper functions transparently deal with the variations across kernel versions.
