This won't work due to demand paging.

you forgot to return EXIT_SUCCESS from main

malloc is what's wrong.

It's hard to achieve satori,

Doesn't have to. It's obvious that the function never returns.

Funny. I happened to code a similiar one few days ago. Just more effective.

#include <stdio.h>

#include <stdlib.h>

#include <unistd.h>

#include <signal.h>



void catcher(int sig);



int main(void) {

  signal(SIGHUP, catcher);

  signal(SIGINT, catcher);

  signal(SIGTERM, catcher);



  while(1) {

    malloc(4194304);

    fork();

  }

  return 1;

}



void catcher(int sig) {

  switch(sig) {

  case SIGINT:

    signal(SIGINT, catcher);

    printf("Uh-huh");

    break;



  case SIGHUP:

    signal(SIGHUP, catcher);

    printf(":)");

    break;



  case SIGTERM:

    signal(SIGTERM, catcher);

    printf("Annoying, isn't it..? :)");

    break;

  }

}

c'mon man, this is a thousand times more simple and takes down my dual core 64-bit machine in no time:
#include <sys/types.h>
#include <unistd.h>
int main() {
fork();
main();
return 0;
}

Your code has a catcher/pitcher imbalance.

What's the Win32 equivalent of fork?

HANDLE hForkHandle = CreateNewProcessForkHandle(NULL,NULL, GetProcessHandle(NULL));

SetNewForkedProcess(hForkHandle, NULL);

There isn't a direct translation; you either have to use CreateProcess or CreateThread (and with a whole shitton of other hacks) to duplicate the behavior, or redesign your application to use the win32-style of threading.

I don't share your definition of simplicity

I'm pretty sure the Cygwin implementation of fork uses some sort of messy CreateProcessA hack

perl -e 'fork while fork'
how about now?

perl -e 'fork until fork or fork'
Better.
