NAME
        DisposeCxMsg -- delete a commodity message. (V36)

   SYNOPSIS
        DisposeCxMsg(cxm);
                     A0

        VOID DisposeCxMsg(struct CxMsg *);

   FUNCTION
        This function eliminates the commodity message pointed to by 'cxm'.
        Can be used to 'swallow' input events by disposing of every commodity
        message of type CXM_IEVENT.

        This function can only be called from within a custom object running
        on the input handler's context. It cannot be called from code running
        on a commodities' context, such as when receiving a CXM_IEVENT message
        from a sender object. CxMsg sent to a commodity program from a sender
        object must be sent back using replymsg().

   INPUTS
        cxm - the commodity message to delete (must NOT be NULL)
