SSL_CTX_free - free an allocated SSL_CTX object
void SSL_CTX_free(SSL_CTX *ctx);
SSL_CTX_free() decrements the reference count of ctx, and removes the SSL_CTX object pointed to by ctx and frees up the allocated memory if the the reference count has reached 0.
It also calls the
free()ing procedures for indirectly affected
items, if applicable: the session cache, the list of ciphers, the list of
Client CAs, the certificates and keys.
If a session-remove callback is set (SSL_CTX_sess_set_remove_cb()), this
callback will be called for each session being freed from ctx's session cache. This implies, that all corresponding sessions from an
external session cache are removed as well. If this is not desired, the
user should explicitly unset the callback by calling
SSL_CTX_sess_set_remove_cb(ctx, NULL) prior to calling
SSL_CTX_free() does not provide diagnostic information.
