NAME
        SetSignal -- define the state of this task's signals

   SYNOPSIS
        oldSignals = SetSignal(newSignals, signalMask)
        D0                     D0          D1

        ULONG SetSignal(ULONG,ULONG);

   FUNCTION
        This function can query or modify the state of the current task's
        received signal mask.  Setting the state of signals is considered
        dangerous.  Reading the state of signals is safe.

   INPUTS
        newSignals - the new values for the signals specified in
                     signalSet.
        signalMask - the set of signals to be affected.

   RESULTS
        oldSignals - the prior values for all signals

   EXAMPLES
        Get the current state of all signals:
            SetSignal(0L,0L);
        Clear the CTRL-C signal:
            SetSignal(0L,SIGBREAKF_CTRL_C);


        Check if the CTRL-C signal was pressed:

            #include <libraries/dos.h>

            /* Check & clear CTRL_C signal */
            if(SetSignal(0L,SIGBREAKF_CTRL_C) & SIGBREAKF_CTRL_C)
                {
                printf("CTRL-C pressed!n");
                }
