I have read some threads here about all the OpenSSL calls being thread-safe, with the notable exception of SSL_read and SSL_write against the same thread. Unfortunately, that's exactly what my program is doing - reading from an SSL on one thread and writing to that same SSL on another. What are the repercussions of doing this? What will go wrong? Is there a list anywhere of exactly what things are and are not thread safe? How is one to know? What do I do to fix my SSL_read and SSL_write problem? Thanks for the help!
