ACL_GET_PERM_NP(3) Library Functions Manual ACL_GET_PERM_NP(3)

acl_get_perm_npcheck if a permission is set in a permission set

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 () 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:

[]
Argument perm does not contain a valid ACL permission or argument permset_d is not a valid ACL permset.
