SSL_CTX_CTRL(3)            Library Functions Manual            SSL_CTX_CTRL(3)

NAME
     SSL_CTX_ctrl, SSL_CTX_callback_ctrl, SSL_ctrl, SSL_callback_ctrl -
     internal handling functions for SSL_CTX and SSL objects

SYNOPSIS
     #include <openssl/ssl.h>

     long
     SSL_CTX_ctrl(SSL_CTX *ctx, int cmd, long larg, void *parg);

     long
     SSL_CTX_callback_ctrl(SSL_CTX *, int cmd, void (*fp)());

     long
     SSL_ctrl(SSL *ssl, int cmd, long larg, void *parg);

     long
     SSL_callback_ctrl(SSL *, int cmd, void (*fp)());

DESCRIPTION
     The SSL_*_ctrl() family of functions is used to manipulate settings of
     the SSL_CTX and SSL objects.  Depending on the command cmd the arguments
     larg, parg, or fp are evaluated.  These functions should never be called
     directly.  All functionalities needed are made available via other
     functions or macros.

RETURN VALUES
     The return values of the SSL*_ctrl() functions depend on the command
     supplied via the cmd() parameter.
