NAME

6       SSL_set_session - set a TLS/SSL session to be used during TLS/SSL
7       connect
8

SYNOPSIS

10        #include <openssl/ssl.h>
11
12        int SSL_set_session(SSL *ssl, SSL_SESSION *session);
13

DESCRIPTION

15       SSL_set_session() sets session to be used when the TLS/SSL connection
16       is to be established. SSL_set_session() is only useful for TLS/SSL
17       clients.  When the session is set, the reference count of session is
18       incremented by 1. If the session is not reused, the reference count is
19       decremented again during SSL_connect(). Whether the session was reused
20       can be queried with the SSL_session_reused(3) call.
21
22       If there is already a session set inside ssl (because it was set with
23       SSL_set_session() before or because the same ssl was already used for a
24       connection), SSL_SESSION_free() will be called for that session. If
25       that old session is still open, it is considered bad and will be
26       removed from the session cache (if used). A session is considered open,
27       if SSL_shutdown(3) was not called for the connection (or at least
28       SSL_set_shutdown(3) was used to set the SSL_SENT_SHUTDOWN state).

NOTES

31       SSL_SESSION objects keep internal link information about the session
32       cache list, when being inserted into one SSL_CTX object's session
33       cache.  One SSL_SESSION object, regardless of its reference count, must
34       therefore only be used with one SSL_CTX object (and the SSL objects
35       created from this SSL_CTX object).
