Описание (Description)
The acl_valid() function checks the ACL referred to by the argument
acl for validity.
The three required entries ACL_USER_OBJ, ACL_GROUP_OBJ, and
ACL_OTHER must exist exactly once in the ACL. If the ACL contains
any ACL_USER or ACL_GROUP entries, then an ACL_MASK entry is also
required. The ACL may contain at most one ACL_MASK entry.
The user identifiers must be unique among all entries of type
ACL_USER. The group identifiers must be unique among all entries
of type ACL_GROUP.
Возвращаемое значение (Return value)
The acl_valid() function returns the value 0 if successful;
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_valid() function
returns -1 and sets errno to the corresponding value:
[EINVAL] The argument acl is not a valid pointer to an
ACL.
The argument acl does not point to a valid ACL.
One or more of the required ACL entries is not
present in acl.
The ACL contains entries that are not unique.
