CR_SEEOTHERUIDS(9)     FreeBSD Kernel Developer's Manual    CR_SEEOTHERUIDS(9)

NAME
     cr_seeotheruids --	determine visibility of	objects	given their user cre-
     dentials

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

DESCRIPTION
     This function determines the visibility of	objects	in the kernel based on
     the real user 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_uids.  If this variable is non-zero	then all
     objects in	the kernel are visible to each other irrespective of their
     user IDs.	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 u1 and u2 have the same real user ID.

SYSCTL VARIABLES
     security.bsd.see_other_uids
	     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.
