-=head1 NAME
-
-SSL_SESSION_free - free an allocated SSL_SESSION structure
-
-=head1 SYNOPSIS
-
- #include <openssl/ssl.h>
-
- void SSL_SESSION_free(SSL_SESSION *session);
-
-=head1 DESCRIPTION
-
-SSL_SESSION_free() decrements the reference count of B<session> and removes
-the B<SSL_SESSION> structure pointed to by B<session> and frees up the allocated
-memory, if the the reference count has reached 0.
-
-=head1 NOTES
-
-SSL_SESSION objects are allocated, when a TLS/SSL handshake operation
-is successfully completed. Depending on the settings, see
-L<SSL_CTX_set_session_cache_mode(3)|SSL_CTX_set_session_cache_mode(3)>,
-the SSL_SESSION objects are internally referenced by the SSL_CTX and
-linked into its session cache. SSL objects may be using the SSL_SESSION object;
-as a session may be reused, several SSL objects may be using one SSL_SESSION
-object at the same time. It is therefore crucial to keep the reference
-count (usage information) correct and not delete a SSL_SESSION object
-that is still used, as this may lead to program failures due to
-dangling pointers. These failures may also appear delayed, e.g.
-when an SSL_SESSION object was completely freed as the reference count
-incorrectly became 0, but it is still referenced in the internal
-session cache and the cache list is processed during a
-L<SSL_CTX_flush_sessions(3)|SSL_CTX_flush_sessions(3)> operation.
-
-SSL_SESSION_free() must only be called for SSL_SESSION objects, for
-which the reference count was explicitly incremented (e.g.
-by calling SSL_get1_session(), see L<SSL_get_session(3)|SSL_get_session(3)>)
-or when the SSL_SESSION object was generated outside a TLS handshake
-operation, e.g. by using L<d2i_SSL_SESSION(3)|d2i_SSL_SESSION(3)>.
-It must not be called on other SSL_SESSION objects, as this would cause
-incorrect reference counts and therefore program failures.
-
-=head1 RETURN VALUES
-
-SSL_SESSION_free() does not provide diagnostic information.
