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"); }
