Sorry, but this in not true. You have to call mysql_thread_init() for each thread that is not calling mysql_real_connect() This is needed to setup some thread local variables MySQL needs to make things threadsafe.

Michael> If the above is incorrect, please let me know. Please read the manual section about how to make a thread safe client. This explains in detail what you have to do!
