I thought fork() didn't work on Win32 systems ? I believe it's a Unix command only and not usable on WinNT, the OS I'm using...	[reply]

To my knowledge, fork() is emulated on Win32 systems using threads, thanks to the good work of Gurusamy Sarathy. Liz	[reply]

It is a good emulation, but it's not perfect. Check out They didn't give me a fork so I have to eat with a spawn. for more details. Specifically, for some ActivePerls, forking more than a certain number of processes (20?) results in "Resource Temporarily Unavailable" errors. -- Mike	[reply]

Contrary to poular myth, fork does work under win32 since at least 5.6. Under the covers it is implemented in exactly the same as threads are. IMO, the threads interface is easier to use than fork, but then I've never really made any great use of fork in C, so I'm coming from a different background. It also has the added bonus of making it reasonably easy to share data between parent and child. Examine what is said, not who speaks.
