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 identi-
       cal 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.
