hi .. I have read these lines..
"Multi-threaded applications must provide two callback functions to OpenSSL by calling CRYPTO_set_locking_callback() and CRYPTO_set_id_callback(), for all versions of OpenSSL up to and including 0.9.8[abc...]. As of version 0.9.9, CRYPTO_set_id_callback() and associated APIs are deprecated by CRYPTO_THREADID_set_callback() and friends. " could anyone suggest me how to use these callback functions as there is not enough help available. Waiting for the reply... Thanx...
