—

Standard C Library (libc, -lc)
#include
<sys/types.h>
#include <sys/acl.h>
int
acl_get_perm_np
(acl_permset_t
permset_d, acl_perm_t
perm);
The
acl_get_perm_np
()
function is a non-portable function that checks if a permission is set in a
permission set.
If the permission in perm is set in the permission set permset_d, a value of 1 is returned, otherwise a value of 0 is returned.
If any of the following conditions occur, the
acl_get_perm_np
() function will return a value of -1
and set global variable errno to the corresponding
value:
EINVAL
]acl(3), acl_add_perm(3), acl_clear_perms(3), acl_delete_perm(3), acl_get_permset(3), acl_set_permset(3), posix1e(3)
POSIX.1e is described in IEEE POSIX.1e draft 17.
