Linux / Unix Command: seteuid

Command Library

NAME

seteuid, setegid - set effective user or group ID  

SYNOPSIS

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

int seteuid(uid_t euid);
int setegid(gid_t egid);  

DESCRIPTION

seteuid sets the effective user ID of the current process. Unprivileged user processes may only set the effective user ID to the real user ID, the effective user ID or the saved user ID.

Precisely the same holds for setegid with "group" instead of "user".

 

RETURN VALUE

On success, zero is returned. On error, -1 is returned, and errno is set appropriately.  

ERRORS

EPERM

The current process is not the super-user and euid (resp. egid) is not the real user (group) ID, the effective user (group) ID or the saved user (group) ID.
