I've already explained the external interface. The internal detiails might not be helpful for providing solution to my problem, but the details will definitely be helpful in understanding how OpenSSL works and what conditions cause these limitations. > > Where exactly would the locking callback functions come into picture? > > The locking callback functions are required to be properly implemented if > you are going to use OpenSSL on a multithreaded platform.
