SSL_set_session(3) — Subroutines

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

The SSL_set_session() function sets session to be used when the TLS/SSL connection is to be established. The SSL_set_session() function 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() function .

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 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:

0The operation failed; check the error stack to find out the reason.

1The operation succeeded.
