NAME

       SSL_set_session - set a TLS/SSL session to be used during TLS/SSL connect

SYNOPSIS

        #include <openssl/ssl.h>

        int SSL_set_session(SSL *ssl, SSL_SESSION *session);

DESCRIPTION

       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. If that old session is still open, it is considered bad and
       will be removed from the session cache (if used). A session is considered open, if
       SSL_shutdown(3) was not called for the connection (or at least SSL_set_shutdown(3) was
       used to set the SSL_SENT_SHUTDOWN state).

NOTES

       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 SSL_CTX object).

RETURN VALUES

       The following return values can occur:

       0   The operation failed; check the error stack to find out the reason.

       1   The operation succeeded.
