SSL_free - free an allocated SSL structure
#include <openssl/ssl.h>
void SSL_free(SSL *ssl);
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 reference count has reached 0. If
ssl is NULL nothing is done.
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.
