CreateProcess() in a client server application

hey,
I am working on a udp client-server application where one server is supposed to handle 40 clients which could all be logged on at once as well...
Now in "unix" such issues are resolved by using "fork()" function which basically creates a child process to deal with the client and leaves the server to accept new connections...
I searched on the internet and found out that an exact analogous of "fork()" is not available in windows, however "CreateProcess()" could be used...
My previous research also introduced me to "thread pool" so now I've two questions:
1)Could I acheive the functionality of "fork()" by "CreateProcess()" in windows.
2)if this is possible,what should I do go for: threadpool or creating multiple processes ?

looking forward to the response...

Solution 1

(1) Both CreateProcess and fork creates a new process. However fork duplicates the calling process, while CreateProcess starts an executable. Both function allows the implementation of a multiprocess server.

(2) Usually such servers are multithreaded, however nothing prevents you to make it multiprocess instead.
Just be aware that inter-process communication is heavier.

So that means I should go for threadpool in order to save the processing power?

You might. Have a look at this page: http://www.zerigo.com/article/apache_multi-threaded_vs_multi-process_pre-forked/
