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.
