Ok I read through the threads chapter (very nice book btw). Now just correct me if I miss understood. I would make a sem_t web_counter; then inside the handler for the webserver I add the sem_wait(&web_counter); then in game loop unix when I want that thread to run I would sem_post(&web_counter); That will allow that thread to run yes?
Now will that run once, and then sit and wait to be posted again? Or would I have to have the handler do something to make sure next time it goes to loop it waits till it's posted? ----- Original Message ----- From: "Yun Zhou" <[EMAIL PROTECTED]> To: "Dale Kingston" <[EMAIL PROTECTED]> Cc: <[email protected]> Sent: Thursday, August 07, 2003 11:46 AM Subject: Re: Threads question > The following is not just a tutorial, but rather, an entire book (completely > free of charge, avaliable online in HTML): > > http://www.newriders.com/books/opl/ebooks/0735710430.html > > Look in chapter 4.
