Member Function Documentation

◆ Create()

BIO * Ssl::Bio::Create ( const int  fd,
Security::Io::Type  type 

Creates a low-level BIO table, creates a high-level Ssl::Bio object for a given socket, and then links the two together via BIO_C_SET_FD.

◆ flush()

virtual void Ssl::Bio::flush ( BIO *  )

Flushes any buffered data to socket. The Ssl::Bio does not buffer any data, so this method has nothing to do

Reimplemented in Ssl::ServerBio.

◆ stateChanged()

void Ssl::Bio::stateChanged ( const SSL *  ssl,
int  where,
int  ret 

Called by linked SSL connection whenever state changes, an alert appears, or an error occurs. See SSL_set_info_callback().

Called whenever the SSL connection state changes, an alert appears, or an error occurs. See SSL_set_info_callback().
