[fpc-pascal] mutexes and semaphores.

[Andreas Berger]

In order to implement threading in DOS I will need to use some type of 
mutex, but would like to implement it the FPC way.


Does FPC implement platform independent mutexes and/or semaphores? Or 
must each platform use it's own OS specific versions?


Regards,
Andreas

Michael Van Canneyt can answer this question, there are some parts in
FCL approaching OS independence.

There is no "FPC way" :-)

Each platform currently uses it's own OS specific version.

For FPC, it should be enough to implement RTLCiticalSection support,
using the thread manager. The Syncobjs unit in the FCL uses that to
implement classes which can be used as a mutex.
