SSL_free(3) OpenSSL SSL_free(3) NAME SSL_free - free an allocated SSL structure LIBRARY libcrypto, -lcrypto SYNOPSIS #include <openssl/ssl.h> void SSL_free(SSL *ssl); DESCRIPTION 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. NOTES 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. RETURN VALUES SSL_free() does not provide diagnostic information. SSL_new(3), SSL_clear(3), SSL_shutdown(3), SSL_set_shutdown(3), ssl(3) 1.0.1u 2009-07-19 SSL_free(3)
