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.
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.
