Hi again Chaos, When your program terminates execution the OS (cwsdpmi or Windoze etc) should handle all the deallocation of the allocated memory used by that program. Phew! At least I don't have to worry about that one. Thnx. So if that "return 1 " statement causes your program to terminate (ie if it's in the main() function) and exit to the OS then you can count on all your previously undeallocated memory being freed. So IMHO say if you allocate a 4M buffer and exit to the OS without freeing it the OS should free it and all the other memory that you process consumed. That's what I wanted exactly to know. Thnx again. However IMHO it might be nice (at least for aesthetic purposes) to write a error handling function which in your case would cleanup the deallocating of previously allocated memory and do other things like restoring hooked interrupt's etc. Yeah, it would be nice. Actually I have such function. > I know I want something very weird ;-) No way! It's not weird at all. I was kidding ;-) Kalum Take care. -=| Chaos |=- e-mail: chengin AT alpha DOT net DOT pl chengin AT polbox DOT com
