       void EZ_DeleteMessageHandler(Atom type, int messageId, void *client_data,

ARGUMENTS
       handler  Specifies a message handler.

       client_data  Specifies an application data to be passed to the handler.

       messageId Specifies a serial number. Serial number is local to each
       application so the sender has to keep track of it.

       timeout Specifies the life span of this handler, in seconds. The
       handler will be deleted after the specified number of seconds elapses.
       If zero or negative, the handler will have an infinite life span.


DESCRIPTION
       EZ_AddMessageHandler registers a message handler with EZWGL. The
       message handler will be invoked when a messages with the specified type
       and serial number arrives.

       EZ_DeleteMessageHandler deletes the registered message handler that
       matches the specification.
