I also should mention that OpenSSL 1.0.2 is missing a lot of macros for manipulating BIO_METHODs.You probably ran into this when you tried to use part 1’s StringBIO.All the functionality is there in 1.0.2; what’s missing are the macros to access it.

The example 'C' program sslconnect.c demonstrates how to make a basic SSL/TLS connection, using the OpenSSL library functions. Example Code Listing BIO_new_buffer_ssl_connect()creates a new BIOchain consisting of a buffering BIO, an SSL BIO(using ctx) and a connect BIO. BIO_ssl_copy_session_id()copies an SSLsession id between BIOchains fromand to. locating the SSLBIOs in each chain and calling SSL_copy_session_id()on the internal SSLpointer. OpenSSL is a software library for applications that secure communications over computer networks against eavesdropping or need to identify the party at the other end. It is widely used by Internet servers, including the majority of HTTPS websites. OpenSSL contains an open-source implementation of the SSL and TLS protocols.

An OpenSSL sink BIO is a BIO that doesn't pass data to another BIO but transfers it to somewhere else (to a file, network, etc.). As regard to source and sink BIOs, there are not specifically source BIOs and there are not specifically sink BIOs, there are only "source-sink" BIOs. The BIO which is a source BIO is a sink BIO as well.
OpenSSL BIO logic doesn't indicate this condition with BIO_should_write() instead it uses BIO_should_io_special(). This is to cover the case where some TCP/IP transport implementation might want to wait for a special condition instead of using writeable for this purpose. 10 #include
