SSL_set_session - set a TLS/SSL session to be used during TLS/SSL connect
int SSL_set_session(SSL *ssl, SSL_SESSION *session);
SSL_set_session() sets session to be used when the TLS/SSL connection is to be established.
SSL_set_session() is only useful for TLS/SSL clients. When the
session is set, the reference count of session is incremented by 1. If the session is not reused, the reference count is
decremented again during
SSL_connect(). Whether the session
was reused can be queried with the SSL_session_reused(3) call.
If there is already a session set inside ssl (because it was set with
SSL_set_session() before or because
the same ssl was already used for a connection),
SSL_SESSION_free() will be
called for that session.
SSL_SESSION objects keep internal link information about the session cache
list, when being inserted into one SSL_CTX object's session cache. One
SSL_SESSION object, regardless of its reference count, must therefore only
be used with one SSL_CTX object (and the SSL objects created from this
