       SSL_CTX_free - free an allocated SSL_CTX object


        #include <openssl/ssl.h>

        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 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 ctx is NULL nothing is done.


       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().


       SSL_CTX_free() does not provide diagnostic information.
