=head1 NAME
-SSL_get_session - retrieve TLS/SSL session data
+SSL_get_session, SSL_get0_session, SSL_get1_session - retrieve TLS/SSL session data
=head1 SYNOPSIS
#include <openssl/ssl.h>
- SSL_SESSION *SSL_get_session(SSL *ssl);
- SSL_SESSION *SSL_get0_session(SSL *ssl);
+ SSL_SESSION *SSL_get_session(const SSL *ssl);
+ SSL_SESSION *SSL_get0_session(const SSL *ssl);
SSL_SESSION *SSL_get1_session(SSL *ssl);
=head1 DESCRIPTION
during L<SSL_CTX_flush_sessions(3)|SSL_CTX_flush_sessions(3)>.
If the data is to be kept, SSL_get1_session() will increment the reference
-count and the session will stay in memory until explicitly freed with
-L<SSL_SESSION_free(3)|SSL_SESSION_free(3)>, regardless of its state.
+count, so that the session will not be implicitly removed by other operations
+but stays in memory. In order to remove the session
+L<SSL_SESSION_free(3)|SSL_SESSION_free(3)> must be explicitly called once
+to decrement the reference count again.
+
+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).
