NAME
        CxSignal -- create a commodity signaller object. (V36)

   SYNOPSIS
        signalerObj = CxSignal(task,signal);

        cxobj *cxsignal(struct task *,long);

   FUNCTION
        This function creates a Commodities signal object. The action
        of this object on receiving a Commodities message is to
        send the 'signal' to the 'task'. The caller is responsible
        for allocating the signal and determining the proper task ID.

        Note that 'signal' is the signal value as returned by allocsignal(),
        not the mask made from that value.

        This function is a C-language macro for createcxobj(), defined
        in <libraries/commodities.h>.

   INPUTS
        task - the task for the signaller to signal
        signal - the signal bit number for the signaller to send

   RESULTS
        signallerObj - a pointer to the signaller object, or NULL if it could
                       not be created.
