NAME
acl_get_perm —
test for a permission in an ACL permission set
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
#include
<sys/types.h>
#include <acl/libacl.h>
int
acl_get_perm(acl_permset_t
permset_d, acl_perm_t
perm);
DESCRIPTION
The
acl_get_perm()
function tests if the permission specified by the argument
perm (one of ACL_READ, ACL_WRITE, ACL_EXECUTE) is
contained in the ACL permission set pointed to by the argument
permset_d.
Any existing descriptors that refer to permset_d continue to refer to that permission set.
RETURN VALUE
If successful, the
acl_get_perm()
function returns 1 if the permission specified by
perm is contained in the ACL permission set
permset_d, and 0 if the
permission is not contained in the permission set. Otherwise, the value
-1 is returned and the global variable
errno is set to indicate the error.
ERRORS
If any of the following conditions occur, the
acl_get_perm() function returns
-1 and sets errno to the
corresponding value:
- [
EINVAL] - The argument permset_d is not a valid descriptor for
a permission set within an ACL entry.
The argument perm is not a valid acl_perm_t value.
STANDARDS
This is a non-portable, Linux specific extension to the ACL manipulation functions defined in IEEE Std 1003.1e draft 17 (“POSIX.1e”, abandoned).
