DESCRIPTION
     The acl_entries() function returns the number of ACL entries that are
     contained in the ACL referred to by the argument acl.

     successful; otherwise the value -1 is returned and the global variable
     errno is set to indicate the error.

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