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");
}
