SSL_CTX_free(3)

     NAME
          SSL_CTX_free - free an allocated SSL_CTX object

     SYNOPSIS
           #include <openssl/ssl.h>

           void SSL_CTX_free(SSL_CTX *ctx);


     DESCRIPTION
          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.

     WARNINGS
          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().

     RETURN VALUES
          SSL_CTX_free() does not provide diagnostic information.
