After fighting with the docs a little bit, here is how to handle an
int/0 in a C application.

#include "stdio.h"
#include "excpt.h"
#include "windows.h"

int HandleException( int iExcept );

int main(int argc, char* argv[])
{int b = 0;int a;
puts("hello");__try{    puts("in try");    a = 0/b;}__except( HandleException(GetExceptionCode()) ){    puts("in
except");}puts("world"); 
}

int HandleException( int iExcept )
{if (iExcept == EXCEPTION_INT_DIVIDE_BY_ZERO) {        puts("Handled int/0 exception");    return
EXCEPTION_EXECUTE_HANDLER;}/*call the system handler and crash */return EXCEPTION_CONTINUE_SEARCH ;      
}

This is not C.
