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.

RESULT

	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");
}
