NAME

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

SYNOPSIS

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

DESCRIPTION

19       The SSL_*_ctrl() family of functions is used to manipulate settings of
20       the SSL_CTX and SSL objects. Depending on the command cmd the arguments
21       larg, parg, or fp are evaluated. These functions should never be called
22       directly. All functionalities needed are made available via other
23       functions or macros.
24

RETURN VALUES

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