=head1 NAME

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

=head1 SYNOPSIS

 #include <openssl/ssl.h>

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

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

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

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

=head1 DESCRIPTION

The SSL_*_ctrl() family of functions is used to manipulate settings of

the SSL_CTX and SSL objects. Depending on the command B<cmd> the arguments

B<larg>, B<parg>, or B<fp> are evaluated. These functions should never

be called directly. All functionalities needed are made available via

other functions or macros.

=head1 RETURN VALUES

The return values of the SSL*_ctrl() functions depend on the command

supplied via the B<cmd> parameter.
