If you read my mail (as quoted above), I clearly stated that it is NOT based on the Delphi one. After all, I brought to attention the Delphi similarities in the FPC code a while back - so I would not introduce copyright code into FPC. >> I just need confirmation that the current implementation in FPC is >> incorrect though. > > It's not incorrect, just inefficient. I have to disagree. The currently class name is TMultiReadExclusiveWriteSynchronizer. The currently implementation does NOT allow multi-read (so the class name totally misleading). It uses a simple Critical Section to block any other threads while reading or writing. At least, the FPC team needs to rename the class to TSimpleRWSync (to be Delphi compatible with the same functionality).
