acl_get_perm_np -- check if a permission is set in a permission set
Standard C Library (libc, -lc)
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
[EINVAL] Argument perm does not contain a valid ACL permission
or argument permset_d is not a valid ACL permset.

function was added in FreeBSD 5.0.
