    8: 
    9:  #include <openssl/ssl.h>
   10: 
   11:  long SSL_CTX_ctrl(SSL_CTX *ctx, int cmd, long larg, void *parg);
   12:  long SSL_CTX_callback_ctrl(SSL_CTX *, int cmd, void (*fp)());
   13: 
   14:  long SSL_ctrl(SSL *ssl, int cmd, long larg, void *parg);
   15:  long SSL_callback_ctrl(SSL *, int cmd, void (*fp)());

   17: =head1 DESCRIPTION
   18: 
   19: The SSL_*_ctrl() family of functions is used to manipulate settings of
   20: the SSL_CTX and SSL objects. Depending on the command B<cmd> the arguments
   21: B<larg>, B<parg>, or B<fp> are evaluated. These functions should never
   22: be called directly. All functionalities needed are made available via
   23: other functions or macros.
   24: 
   25: =head1 RETURN VALUES
   26: 
   27: The return values of the SSL*_ctrl() functions depend on the command
   28: supplied via the B<cmd> parameter.
