setregid

SETREGID(2)						      BSD System Calls Manual						       SETREGID(2)

NAME

     setregid -- set real and effective group ID

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <unistd.h>

     int
     setregid(gid_t rgid, gid_t egid);

DESCRIPTION

     The real and effective group ID's of the current process are set to the arguments.  Unprivileged users may change the real group ID to the
     effective group ID and vice-versa; 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 substitute the current ID in place of the -1 parame-
     ter.

     The setregid() function was intended to allow swapping the real and effective group IDs in set-group-ID programs to temporarily relinquish
     the set-group-ID value.  This function did not work correctly; its purpose is now better served by the use of the setegid() function (see
     setuid(2)).

     When setting the real and effective group IDs to the same value, the standard setgid() function is preferred.

RETURN VALUES

     The setregid() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indi-
     cate the error.

ERRORS

     [EPERM]		The current process is not the super-user and a change other than changing the effective group-id to the real group-id was
			specified.

SEE ALSO

     getgid(2), issetugid(2), setegid(2), setgid(2), setuid(2)

HISTORY

     The setregid() system call appeared in 4.2BSD.
