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

NAME

     cr_cansee -- determine visibility of objects given their user credentials

SYNOPSIS

     #include <sys/param.h>
     #include <sys/systm.h>
     #include <sys/ucred.h>

     int
     cr_cansee(struct ucred *u1, struct ucred *u2);

DESCRIPTION

     This function determines the visibility of objects in the kernel based on the real user IDs and group IDs in the credentials u1 and u2 asso-
     ciated with them.

     The visibility of objects is influenced by the sysctl(8) variables security.bsd.see_other_gids and security.bsd.see_other_uids, as per the
     description in cr_seeothergids(9) and cr_seeotheruids(9) respectively.

RETURN VALUES

     This function returns zero if the object with credential u1 can ``see'' the object with credential u2, or ESRCH otherwise.

ERRORS

     [ESRCH]		The object with credential u1 cannot ``see'' the object with credential u2.

     [ESRCH]		The object with credential u1 has been jailed and the object with credential u2 does not belong to the same jail as u1.

     [ESRCH]		The MAC subsystem denied visibility.
