signal() funtion

[jarpp]

I'd likie to response for the signals in my application.
How to do it? Code bellow doesn't work no signal is catched, why?
Only if I send the specified signal using raise function handler function is
called.
System platform WinNT 4.0, Win 2000.


void (*oldTerminateHandler)(int);

void terminateHandler(int par)
{
MessagePopup("Info","Signal catched- 'Terminate execution";
}

int main(void)
{
double val =0.0;

oldTerminateHandler = signal (SIGFPE terminateHandler);
val = 1.0 / val; // division by zero so signal should be sent to
application
}

Actually, this function is part of ANSI C standard so we have to include it to be compliant. However, Windows OS's do not support these signals. UNIX systems do support these signals. I will make a note to change the help for this function to reflect that Windows OS's do not support these signals.

OK.
So how to detect 'abnormal program termination'?
I'd like to write some information about crash to log file, is it possible?

There isn't a CVI function. It would have to be through SDK programming, but I don't have any experience with it so I'm not sure what the functions would be.
