CR_SEEOTHERGIDS(9)	 BSD Kernel Developer's	Manual	    CR_SEEOTHERGIDS(9)

NAME
     cr_seeothergids --	determine visibility of	objects	given their group mem-
     berships

SYNOPSIS
     int
     cr_seeothergids(struct ucred *u1, struct ucred *u2);

DESCRIPTION
     This function determines the visibility of	objects	in the kernel based on
     the group IDs in the credentials u1 and u2	associated with	them.

     The visibility of objects is influenced by	the sysctl(8) variable
     security.bsd.see_other_gids.  If this variable is non-zero	then all ob-
     jects in the kernel are visible to	each other irrespective	of their group
     membership.  If this variable is zero then	the object with	credentials u2
     is	visible	to the object with credentials u1 if either u1 is the super-
     user credential, or if at least one of u1's group IDs is present in u2's
     group set.

SYSCTL VARIABLES
     security.bsd.see_other_gids
	     Must be non-zero if objects with unprivileged credentials are to
	     be	able to	see each other.

RETURN VALUES
     This function returns zero	if the object with credential u1 can "see" the
     object with credential u2,	or ESRCH otherwise.
