Threads not copied while forking?

Question

I have one application which has several different threads. Then I forked with fork() but found the child process has to recreate those threads. Is that possible to copy the threads during the clone? Thanks!

If you are using Unix, in C then the fork() should be creating all the new threads, if you are forking after the threads have been created, but this will lead to duplicating of using resources, so can be a problem.

This article talks about a problem using fork in a multi-threaded application, and they reference a web page and the page is below: http://www.viraj.org/b2evolution/blogs/index.php/2007/02/10/threads_and_fork_a_bad_idea
