Имя (Name)

acl_cmp — compare two ACLs

---

Библиотека (Library)

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

---

Синопсис (Synopsis)

#include <sys/types.h>
     #include <acl/libacl.h>

     int
     acl_cmp(acl_t acl1, acl_t acl2);

Описание (Description)

The acl_cmp() function compares the ACLs pointed to by the
     arguments acl1 and acl2 for equality. The two ACLs are considered
     equal if for each entry in acl1 there is an entry in acl2 with
     matching tag type, qualifier, and permissions, and vice versa.

---

Возвращаемое значение (Return value)

If successful, the acl_cmp() function returns 0 if the two ACLs
     acl1 and acl2 are equal, and 1 if they differ. Otherwise, the value
     -1 is returned and the global variable errno is set to indicate the
     error.

---

Ошибки (Error)

If any of the following conditions occur, the acl_cmp() function
     returns -1 and sets errno to the corresponding value:

     [EINVAL]           The argument acl1 is not a valid pointer to an
                        ACL.

                        The argument acl2 is not a valid pointer to an
                        ACL.

---

Стандарты (Conforming to)

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