avc_compute_create

avc_compute_create(3)					     SELinux API documentation					     avc_compute_create(3)

NAME

       avc_compute_create, avc_compute_member - obtain SELinux label for new object

SYNOPSIS

       #include <selinux/selinux.h>
       #include <selinux/avc.h>

       int avc_compute_create(security_id_t ssid, security_id_t tsid,
			      security_class_t tclass, security_id_t *newsid);

       int avc_compute_member(security_id_t ssid, security_id_t tsid,
			      security_class_t tclass, security_id_t *newsid);

DESCRIPTION

       avc_compute_create()  is  used  to  compute a SID to use for labeling a new object in a particular class based on a SID pair.  This call is
       identical to security_compute_create(), but does not require converting from userspace SID's to contexts and back again.

       avc_compute_member() is used to compute a SID to use for labeling a polyinstantiated object instance of a particular class based on  a  SID
       pair.   This  call  is  identical  to  security_compute_member(), but does not require converting from userspace SID's to contexts and back
       again.

       These functions return a SID for the computed context in the memory referenced by sid.

RETURN VALUE

       On success, zero is returned.  On error, -1 is returned and errno is set appropriately.

ERRORS

       EINVAL The tclass and/or the security contexts referenced by ssid and tsid are not recognized by the currently loaded policy.

       ENOMEM An attempt to allocate memory failed.
