SETREGID(2)							   SETREGID(2)

NAME    [Toc]    [Back]

     setregid -	set real and effective group ID

SYNOPSIS    [Toc]    [Back]

     #include <unistd.h>

     int setregid (gid_t rgid, gid_t egid);

DESCRIPTION    [Toc]    [Back]

     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	parameter.

RETURN VALUE    [Toc]    [Back]

     Upon successful completion, a value of 0 is returned.  Otherwise, a value
     of	-1 is returned and errno is set	to indicate the	error.

ERRORS    [Toc]    [Back]

     [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.
