\membersection{wxProtocol::Reconnect}\label{wxprotocolreconnect}

\func{bool}{Reconnect}{\void}

Tries to reestablish a previous opened connection (close and renegotiate connection).

\wxheading{Return value}

true, if the connection is established, else false.

\membersection{wxProtocol::GetInputStream}\label{wxprotocolgetinput}

\func{wxInputStream *}{GetInputStream}{\param{const wxString\&}{ path}}

Creates a new input stream on the specified path. You can use all but seek
functionality of wxStream. Seek isn't available on all streams. For example,
HTTP or FTP streams don't deal with it. Other functions like StreamSize and
Tell aren't available for the moment for this sort of stream.
You will be notified when the EOF is reached by an error.

\wxheading{Return value}

Returns the initialized stream. You will have to delete it yourself once you
don't use it anymore. The destructor closes the network connection.

\membersection{wxProtocol::Abort}\label{wxprotocolabort}

\func{bool}{Abort}{\void}

Abort the current stream.

\wxheading{Warning}

It is advised to destroy the input stream instead of aborting the stream this way.

\wxheading{Return value}

Returns true, if successful, else false.
