In what moment i need call the function GetThreadManager to get it and use semaphore* functions?

Each time i will use some of the functions (a sequence of them), a "per-thread" basis or i can discover it only one time, set for example to a global and use the global aways?

You should never do that. The thread manager is internal. For example, the semaphore* functions are nil in the Windows, see http://bugs.freepascal.org/view.php?id=11206

I don't know whether, and if so in which unit, any semaphore functions are published.

But then, what is this post about?

So, who i use semaphores on linux? (i want Unix like, specifically Linux. For windows i´m using it´s own API)

Léo Willian Kölln

Bad advice. Mea culpa.

Jonas

So... What i do now?
There is no way to use semaphores on Linux?
Not even using a syscall or something?
The bad advice is this one or the one from the link i passed?

Léo Willian Kölln

Of course there is (the pthreads unit). I just don't know whether there is a cross-platform unit with semaphore-functionality in FPC.

Jonas

OK!

I will take a look at the pthreads unit. Maybe i make a multi-platform(windows/linux) syncronization unit for the project i´m on and i will try publish it.

Thank you Jonas!
