1=pod 2 3=head1 NAME 4 5SSL_CTX_ctrl, SSL_CTX_callback_ctrl, SSL_ctrl, SSL_callback_ctrl - internal handling functions for SSL_CTX and SSL objects 6 7=head1 SYNOPSIS 8 9 #include <openssl/ssl.h> 10 11 long SSL_CTX_ctrl(SSL_CTX *ctx, int cmd, long larg, void *parg); 12 long SSL_CTX_callback_ctrl(SSL_CTX *, int cmd, void (*fp)()); 13 14 long SSL_ctrl(SSL *ssl, int cmd, long larg, void *parg); 15 long SSL_callback_ctrl(SSL *, int cmd, void (*fp)()); 16 17=head1 DESCRIPTION 18 19The SSL_*_ctrl() family of functions is used to manipulate settings of 20the SSL_CTX and SSL objects. Depending on the command B<cmd> the arguments 21B<larg>, B<parg>, or B<fp> are evaluated. These functions should never 22be called directly. All functionalities needed are made available via 23other functions or macros. 24 25=head1 RETURN VALUES 26 27The return values of the SSL*_ctrl() functions depend on the command 28supplied via the B<cmd> parameter. 29 30=head1 SEE ALSO 31 32L<ssl(7)> 33 34=head1 COPYRIGHT 35 36Copyright 2001-2016 The OpenSSL Project Authors.
