Hi,
I'm a bit confused about usage of SSL_write()/SSL_read() in
non-blocking connectors. Let say I do SSL_write() and I get
SSL_ERROR_WANT_WRITE. It means I have to do SSL_write() again. But does
it mean that I can't do SSL_read() until SSL_write() returns with
success?
Any idea?

My understanding is that yes, on that given socket, you have to do only
what it needs according to the error code. In this case,
SSL_ERROR_WANT_WRITE indicates you should select on write and try
SSL_write() again before doing an SSL_read() on that socket. Of course,
you can read and write on
If SSL_read returns SSL_ERROR_WANT_READ, it is perfectly reasonable to
go ahead and call SSL_write or the other way around. Otherwise, it
would be impossible to do full-duplex SSL communication with OpenSSL.
I recently ran into a host of similar questions (and issues) and I got
most of my
