Non-Blocking Socket Reads and Writes?

[Chris Rowe]

I am having a hard time finding a good example on using non-blocking I/O with SSL_Read and SSL_Write? How do I set the underlying BIO to non-blocking? I am assuming it requires the use of SSL_ERROR_WANT_READ or SSL_peek()??? I have been looking in the man pages on openssl but need a little push in the right direction please.   Thanks in advance, Chris Rowe
