Re: calling SSL_library_init multiple times
Hi Randy, Thanks for the effort and the reply. I have changed the design of my library interface to the applications to include a init call so that I do not need to worry about this.

I don't think that's what was intended. I think the last sentence is more accurate – if you have a multi-threaded application, and you've "hooked" the static and dynamic mutex functions to allow OpenSSL to correctly operate in a multi-threaded environment, then SSL_library_init() should only be called once, during application initialization. This single call will initialize the library for all threads. This is my interpretation of from what I have gleaned from the docs and sources.

Jagannadha Bhattu G [EMAIL PROTECTED]: Hi, Can I call SSL_library_init multiple times in my code under different threads? From the documented return values, I conclude that it should be possible. Can some one confirm it? Thanks JB Yes it's possible. I'm doing like this for now... , but I'm not shure whether this is correct... //wbr - Andrew __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
