Hi again, I'm trying to follow the instructions in the OpenSSL reference book, and their example code from their site for setting a socket to 'non-blocking'.
Before I made any changes, I was working with good code that was making secure connections with no problems. Essentially: bio = BIO_new_connect(connect_str); BIO_do_connect(bio); ssl = SSL_new(ctx); SSL_set_bio(ssl, bio, bio); SSL_connect(ssl); >From the example code, it seemed easy enough to call 'SSL_get_rfd() using the SSL object to get the file descriptor in order to use fcntl() to change the socket to non-blocking. However when I did this, calls to SSL_get_rfd() always return -1. Reading the function description docs, SSL_get_rfd() will return -1 if the BIO is not "suitable for file descriptors". The example code doesn't show how their BIO & SSL objects were created, and there's no other reference or information on what they mean on how to make them 'suitable'. So, I tried another approach. I created a socket the convention way and did a connect, followed by: bio = BIO_new_socket(sd, BIO_CLOSE); ssl = SSL_new(ctx) ; SSL_set_bio(ssl, bio, bio); SSL_connect(ssl); which also worked....until I called SSL_get_rfd() after I created the SSL object, which again returned -1. What am I doing wrong? How do you make a BIO object for file descriptors suitable? thanx /carl h. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
