SSL_free(3)SSL_free(3)NAMESSL_free - Free an allocated SSL structure
SSL *ssl );
The SSL_free() function decrements the reference count of ssl, and
removes the SSL structure pointed to by ssl and frees up the allocated
memory if the the reference count has reached 0.
The SSL_free() function also calls the freeing procedures for indi‐
rectly affected items, if applicable: the buffering BIO, the read and
write BIOs, cipher lists specially created for this ssl, the SSL_SES‐
SION. Do not explicitly free these indirectly freed up items before or
after calling the SSL_free() function. Trying to free things twice may
lead to program failure.
The ssl session has reference counts from two users: the SSL object,
for which the reference count is removed by the SSL_free() function and
the internal session cache. If the session is considered bad, because
the SSL_shutdown() function was not called for the connection and the
SSL_set_shutdown() function was not used to set the SSL_SENT_SHUTDOWN
state. The session will also be removed from the session cache as
required by RFC2246.
The SSL_free() function does not provide diagnostic information.
