Is there any alternative API for SSL_CTX_load_verify_locations? SSL_CTX_load_verify_location ends up using STDIO calls and i am trying to avoid STDIO calls.
I am stuck here and i need yr help to proceed further. Any help is appreicated.

What you're missing is that the OpenSSL engine is the boss of what to do when. You have to do four things, and you must do each one when the OpenSSL engine tells you to: 1) You must receive encrypted data from the other end and hand it to OpenSSL. 2) You must take encrypted data from OpenSSL and send it to the other end. 3) You must take plaintext from the application and give it to OpenSSL to encryptd. 4) You must take plaintext from OpenSSL and process it. Do not ever assume that because you did 1, you will next do 4. This might happen, but it might not. Assumptions will lead to deadlock.
