Using pthread_mutex_lock

[eddyq]

On Windows there is a function called EnterCriticalSection. It will not block if the same thread calls it more than once. I want to do the same thing on Linux and was trying pthread_mutex_lock. But that does not check to see if it is the same thread and will still block if the same thread calls it twice (a deadlock).

Is there a pthread_mutex that will do the same thing as EnterCriticalSection?

Use Boost's recursive_mutex.

It looks like trylock should work. Thanks.

No, you need a recursive lock.

sa? O.o (the post I was asking about the "sa?" from, was remoed)

Recursive lock. Yea, I noticed that and should have gotten back to you.
