SSL_free(3) OpenSSL SSL_free(3)
SSL_free - free an allocated SSL structure
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 the reference count has reached 0.
SSL_free() also calls the free()ing procedures for indirectly affected items, if applica-
ble: 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 refer-
ence count is removed by SSL_free() and the internal session cache. If the session is con-
sidered bad, because SSL_shutdown(3) was not called for the connection and SSL_set_shut-
down(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.
