Синопсис (Synopsis)

     acl_t
     acl_dup(acl_t acl);

Описание (Description)

The acl_dup() function returns a pointer to a copy of the ACL
     pointed to by acl.

     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_dup()
     as an argument.

---

Возвращаемое значение (Return value)

On success, this function returns a pointer to the 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_dup() function
     returns a value of (acl_t)NULL and sets errno to the corresponding
     value:

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

     [ENOMEM]           The acl_t to be returned requires more memory
                        than is allowed by the hardware or system-
                        imposed memory management constraints.
