I have no idea what IO completion ports are; but BIO_f_ssl most
probably is not the solution you are looking for. It is a filter BIO
module that you have to push on top of some other BIO module to use
it. For example, BIO_new_ssl_connect combines BIO_f_ssl with
BIO_s_connect.
I intend to write an additional BIO module BIO_pair, which will allow
applications to handle data in whatever way they want to: The program
will have to relay all data between the SSL library and some "real"
I/O ports. I don't think this is currently possible using any of the
existing modules.
