The acl_copy_int() function copies an access control list from user-managed space to system-managed space. When you're finished with the ACL, you should call acl_free() to release it.
A pointer to the ACL in working storage, or NULL if an error occurred (errno is set).
- The buffer doesn't contain a valid external-form ACL.
- There wasn't enough memory to create the ACL in working storage.
- The ACL type isn't ACL_TYPE_ACCESS or ACL_TYPE_DEFAULT.
This function is based on the withdrawn POSIX draft P1003.1e.
