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");
            }
