for a few BIO routines.

+=head1 NAME
+
+SSL_set_session - Set an SSL session to be used during SSL connect
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ int *SSL_set_session(SSL *ssl, SSL_SESSION *session);
+
+=head1 DESCRIPTION
+
+SSL_set_session() sets B<session> to be used, when the SSL connection
+is to be established. SSL_set_session() is only useful for SSL clients.
+When the session is set, the reference count of B<session> is incremented
+by 1. If the session is not reused, the reference count is decremented
+again during SSL_connect().
+
+If there is already a session set inside B<ssl> (because it was set with
+SSL_set_session() before or because the same B<ssl> was already used for
+a connection) SSL_SESSION_free() will be called for that session.
