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.
