The reference count of the B<SSL_SESSION> is not incremented, so +that the pointer can become invalid by other operations. + +SSL_get0_session() is the same as SSL_get_session(). + +SSL_get1_session() is the same as SSL_get_session(), but the reference +count of the B<SSL_SESSION> is incremented by one. + +=head1 NOTES + +The ssl session contains all information required to re-establish the +connection without a new handshake. + +SSL_get0_session() returns a pointer to the actual session. As the +reference counter is not incremented, the pointer is only valid while +the connection is in use. If L<SSL_clear(3)|SSL_clear(3)> or +L<SSL_free(3)|SSL_free(3)> is called, the session may be removed completely +(if considered bad), and the pointer obtained will become invalid. Even +if the session is valid, it can be removed at any time due to timeout +during L<SSL_CTX_flush_sessions(3)|SSL_CTX_flush_sessions(3)>. + +If the data is to be kept, SSL_get1_session() will increment the reference +count, so that the session will not be implicitly removed by other operations +but stays in memory. In order to remove the session +L<SSL_SESSION_free(3)|SSL_SESSION_free(3)> must be explicitly called once +to decrement the reference count again. + +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). + +=head1 RETURN VALUES + +The following return values can occur: + +=over 4 + +=item NULL + +There is no session available in B<ssl>. + +=item Pointer to an SSL + +The return value points to the data of an SSL session. + +=back + +=head1 SEE ALSO + +L<ssl(3)|ssl(3)>, L<SSL_free(3)|SSL_free(3)>, +L<SSL_clear(3)|SSL_clear(3)>, +L<SSL_SESSION_free(3)|SSL_SESSION_free(3)> + +=cut |
