| =head1 NAME |
| |
| SSL_set_session - set a TLS/SSL session to be used during TLS/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 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 B<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 L<SSL_session_reused(3)> call. |
| |
| 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. |
| This is also the case when B<session> is a NULL pointer. If that old |
| session is still B<open>, it is considered bad and will be removed from the |
| session cache (if used). A session is considered open, if L<SSL_shutdown(3)> was |
| not called for the connection (or at least L<SSL_set_shutdown(3)> was used to |
| set the SSL_SENT_SHUTDOWN state). |
| |
| =head1 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). |
| |
| =head1 RETURN VALUES |
| |
| The following return values can occur: |
| |

| |
| =item Z<>1 |
| |
| The operation succeeded. |
