Re: request for thread safety advice

If the library you are wrapping is not threadsafe, one approach is to simply not worry about it and just mark your extension as not being safe to use in a threaded environment. The majority of people use PHP in a non-threaded environment anyway. If you want to be nice to the folks who do use PHP in a threaded environment, you can look into adding a semaphore lock around the calls into the code that is not threadsafe. Such a semaphore lock makes sure that only 1 thread at a time can enter the code. Other threads sit around and wait until it is their turn. -Rasmus On Mon, 20 Oct 2003, netcat wrote: > Hi, internals. > > Please send me (post here i mean) a few links about > 1. thread safety in general > 2. thread saftey in php > 3.
