Notes :
-
+
The implementation is very close to the phtreads implementation, the reason for
using MPServices is the fact that these are also available under OS 9. Thus allowing
for one common API for all current builds.
-
+
As soon as wxThreads are on a 64 bit address space, the TLS must be extended
to use two indices one for each 32 bit part as the MP implementation is limited
to longs.
-
+
I have two implementations for mutexes :
- version A based on a binary semaphore, problem - not reentrant, version B based
+ version A based on a binary semaphore, problem - not reentrant, version B based
on a critical region, allows for reentrancy, performance implications not
yet tested
The same for condition internal, one implementation by Aj Lavin and the other one
copied from the thrimpl.cpp which I assume has been more broadly tested, I've just
- replaced the interlock increment with the appropriate PPC calls
