And you haven't considered multiprocessor systems. They aren't that rare: all newer Pentium 4 systems have two logical cores. The harm would be a failed connection attempt - I don't think that this is acceptable. Hmm. Is libpq a .DLL? Then you could initialize the mutex in DllMain(). Otherwise create a C++ class with one instance and a constructor. Then initialize the mutex from the constructor. -- Manfred
