The method_attrlist Interface
attrtab **method_attrlist (void *handlep);
The handlep parameter is a handle to the load module opened with the method_open interface. method_attrlist provides a means of defining attributes for a loadable module. Authentication-only modules may use this interface to override attributes which would normally come from the identification module half of a compound load module.
method_attrlist is called when a loadable module is first initialized. The return value will be saved for use by later calls to various identification and authentication functions.
