[openssl-users] Root-Level queries while using SSL-connections wrapping "sockets"

I understand the basic gist of setting up SSL-connections using
OpenSSL, as per
However, I am a bit unsure about certain implementations.
In particular (let's talk only about the client-side), I wonder how do
the following methods work internally ::
* SSL_connect (implicitly involving underlying-socket-reads and
* SSL_write (involving underlying-socket-writes)
* SSL_read (involving underlying-socket-reads)
We have a framework which we have ported to a variety of devices,
involving GPRS-connectivity, and devices without operating-systems.
I know that there is "no one universal socket-write" and "no one
universal socket-read" implementations.
With the above in mind, I wonder how the "SSL_connect", "SSL_write",
"SSL_read" actually handle the root-level writes/reads (given that we
do not pass any "root-level-socket-write" and "root-level-socket-read"
callbacks before "SSL_write" and "SSL_read").
Looking forward to some help; I will be grateful for any pointers.
Thanks and Regards,
