Un-privileged users may change the real group ID + to the effective group ID and vice-versa. + + Prior to Linux 1.1.38, the saved ID paradigm, when used + with setregid or setegid was broken. Starting at 1.1.38, + it is also possible to set the effective group ID from the + saved user ID. + + Only the super-user may make other changes. + + Supplying a value of -1 for either the real or effective + group ID forces the system to leave that ID unchanged. + + Currently (libc-4.x.x), setegid(egid) is functionally + equivalent to setregid(-1, egid). + + If the real group ID is changed or the effective group ID + is set to a value not equal to the previous real group ID, + the saved group ID will be set to the new effective group + ID. + +<h3>RETURN VALUE +</h3> On success, zero is returned. On error, -1 is returned, + and errno is set appropriately. + +<h3>ERRORS +</h3> EPERM The current process is not the super-user and + changes other than (i) swapping the effective + group ID with the real group ID or (ii) setting + one to the value of the other or (iii) setting the + effective group ID to the value of the saved group + ID was specified. + +<h3>HISTORY +</h3> The setregid function call appeared in BSD 4.2. + +<h3>CONFORMING TO +</h3> BSD 4.3 + +</pre> +<hr> +<h3>SEE ALSO +</h3><p> +<a href=getgid.htm>getgid</a>, +<a href=setgid.htm>setgid</a>, +<pre> + + + + + +<h3>Linux 1.1.38 2nd August 1994 1 +</h3> + +
