=pod =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 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)()); =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 the arguments B, B, or B 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 parameter. =head1 SEE ALSO L =head1 COPYRIGHT Copyright 2001-2016 The OpenSSL Project Authors.
