5 SSL_free - free an allocated SSL structure
9 #include <openssl/ssl.h>
11 void SSL_free(SSL *ssl);
15 SSL_free() decrements the reference count of B<ssl>, and removes the SSL
16 structure pointed to by B<ssl> and frees up the allocated memory if the
17 reference count has reached 0.
18 If B<ssl> is NULL nothing is done.
22 SSL_free() also calls the free()ing procedures for indirectly affected items, if
23 applicable: the buffering BIO, the read and write BIOs,
24 cipher lists specially created for this B<ssl>, the B<SSL_SESSION>.
25 Do not explicitly free these indirectly freed up items before or after
26 calling SSL_free(), as trying to free things twice may lead to program
29 The ssl session has reference counts from two users: the SSL object, for
30 which the reference count is removed by SSL_free() and the internal
31 session cache. If the session is considered bad, because
32 L<SSL_shutdown(3)> was not called for the connection
33 and L<SSL_set_shutdown(3)> was not used to set the
34 SSL_SENT_SHUTDOWN state, the session will also be removed
35 from the session cache as required by RFC2246.
39 SSL_free() does not provide diagnostic information.
