Re: [fpc-pascal] RTL semaphore supported?
It's not implemented yet, see https://bugs.freepascal.org/view.php?id=37440. For unix systems the pthread.inc already contains the API headers for the sem_* functions ( https://svn.freepascal.org/cgi-bin/viewvc.cgi/trunk/rtl/linux/pthread.inc?view=markup&sortby=file#l183) but for Mac OS X 10.4.8 the dynamic loading of sem_init needs to be implemented ( https://svn.freepascal.org/cgi-bin/viewvc.cgi/trunk/rtl/darwin/pthread.inc?view=markup&sortby=file#l71) and also another way to init a semaphore. For Windows, see https://docs.microsoft.com/en-us/windows/win32/sync/using-semaphore-objects. Am Do., 13.

The way to go with semaphores would be to implement the Delphi compatible TSemaphore in the unit SyncObjs. Well, there's the functionality related to events (= event semaphores) - BasicEvent* / RTLEvent*, and there's also the functionality of critical sections (*CriticalSection) which is basically a mutex semaphore. Obviously, that doesn't contradict the intention to provide the functionality in SyncObjs in Delphi compatible way.
