SSL_FREE(3) Library Functions Manual SSL_FREE(3)

SSL_freefree an allocated SSL structure

#include <openssl/ssl.h>

void
SSL_free(SSL *ssl);

() 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.

SSL_free() also calls the free(3)ing procedures for indirectly affected items, if applicable: the buffering BIO, the read and write BIOs, cipher lists specially created for this ssl, the . 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 () 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.
