I think what you are looking for is here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/base/creating_processes.asp
beware, however, that the "Spork" function and fork() are more-or-less
completely different. That spork code is just a cheap-and-dirty way to
invoke yourself. This means that:
o spork only returns once
o the child process doesn't inherit state from the parent process
o it will only work for processes for which you control the source;
dll's can't do it this way.
I think, long ago, I saw seen some clever folks attempt to implement
fork() like behavior for windows; if you need the "real deal," you
might be able to find this with some googling, or maybe cygwin has
ideas you could borrow.

Do you frequently think "there ought to be a law..."?
Afraid that people you /don't like/ have too much FREEDOM?
Concerned about the unequal powers of the EVIL RICH?
Think the government could solve your neighbor's problems?
You aren't the first.
