[Tinycc-devel] Testing Console Application with CreateProcess

[gregr]

I'm writing a small app to do automated testing of a console application. It
needs to repeatedly run the app with various options and handle when the app
being tested crashes. I started with system(), moved on to spawn() and have
since been trying CreateProcess(). It starts the app correctly but I can't
seem to kill the process. How do I kill the process or is there a different
approach I should consider?

  /* print out our process ID */
  printf("Process %d reporting for duty\n",GetCurrentProcessId());

  /* Get startup info for current process, we will use this
     as the startup info for the new process as well... */
  GetStartupInfo(&si);

  /* Call CreateProcess, telling it to run DivideByZero
     with lots of defaults... (the NULLs mean "use defaults")

//DivideByZero

#include <stdio.h>

int main(void)
{
        int result = 0;

        printf("DivideByZero is about to crash\n");

        result = 42/result;

        printf("Result: %d\n", result);

    return(0);
