ACL_GET_PERM(3)          Library Functions Manual        ACL_GET_PERM(3)

ИМЯ

       acl_get_perm — test for a permission in an ACL permission set

БИБЛИОТЕКА

       Linux Access Control Lists library (libacl, -lacl).

СИНТАКСИС

       <sys/types.h> <acl/libacl.h> int acl_get_perm(acl_permset_t
       permset_d, acl_perm_t perm)

ОПИСАНИЕ

       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.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       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.

ОШИБКИ

       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.

СТАНДАРТЫ

       This is a non-portable, Linux specific extension to the ACL
       manipulation functions defined in IEEE Std 1003.1e draft 17
       (“POSIX.1e”, abandoned).
