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(3) 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 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.
