SSL_free — free an allocated SSL structure
SSL_free() 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.
SSL_free() also calls the free()ing procedures for indirectly
affected items, if applicable: the buffering BIO, the read and write
BIOs, cipher lists specially created for this ssl, the SSL_SESSION.
Do not explicitly free these indirectly freed up items before or
after calling SSL_free(), as 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 SSL_free() and
the internal session cache. If the session is considered bad, because SSL_shutdown(3) was not
called for the connection and SSL_set_shutdown(3) was not used to set the
SSL_SENT_SHUTDOWN state, the session will also be removed from the
session cache as required by RFC2246.
SSL_free() does not provide diagnostic information.
