Имя (Name)

---

Библиотека (Library)

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

Синопсис (Synopsis)

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

     acl_t
     acl_copy_int(const void *buf_p);

Описание (Description)

The acl_copy_int() function copies an exportable, contiguous,
     persistent form of an ACL, pointed to by buf_p, to the internal
     representation.

     This function may cause memory to be allocated.  The caller should
     free any releasable memory, when the new ACL is no longer required,
     by calling acl_free(3) with the (void*)acl_t returned by
     acl_copy_int() as an argument.

---

Возвращаемое значение (Return value)

Upon success, the acl_copy_int() function returns a pointer that
     references the ACL in working storage.  On error, a value of
     (acl_t)NULL is returned, and errno is set appropriately.

---

Ошибки (Error)

If any of the following conditions occur, the acl_copy_int()
     function returns a value of (acl_t)NULL and sets errno to the
     corresponding value:

     [EINVAL]           The buffer pointed to by the argument buf_p does
                        not contain a valid external form ACL.

     [ENOMEM]           The ACL working storage requires more memory
                        than is allowed by the hardware or system-
                        imposed memory management constraints.
