Re: Terminating a program

If you're on NT-based Windows, just killing the process will work. It's 
a real OS with a real kernel, so all resources will be magically 
released (barring any driver bugs, of course).(*)

If you want this on Win98 or WinME, you're screwed, though. Similarly, 
if there's any state you might want to re-use (such as files being 
written to at any point in your program), there's no guarantee of their 
consistency.

Cheers,

(*) This is why I usually advocate implementing "quit" as "exit(0)" 
rather than fully releasing everything, because to release everything, 
you have to walk through it, probably paging in a bunch of cruft just to 
tell the runtime library you don't need it. I hate applications that 
take 20 seconds to quit. The kernel can do a much better job of just 
making it go away on quit than you can.
