\membersection{wxFTP::SendCommand}

\func{bool}{SendCommand}{\param{const wxString\&}{ command}, \param{char }{ret}}

Send the specified \it{command} to the FTP server. \it{ret} specifies
the expected result.

\wxheading{Return value}

TRUE, if the command has been sent successfully, else FALSE.

% ----------------------------------------------------------------------------

\membersection{wxFTP::GetLastResult}

\func{const wxString\&}{GetLastResult}{\void}

Returns the last command result.

% ----------------------------------------------------------------------------

\membersection{wxFTP::ChDir}

\func{bool}{ChDir}{\param{const wxString\&}{ dir}}

Change the current FTP working directory.
Returns TRUE if successful.

\membersection{wxFTP::MkDir}

\func{bool}{MkDir}{\param{const wxString\&}{ dir}}

Create the specified directory in the current FTP working directory.
Returns TRUE if successful.

\membersection{wxFTP::RmDir}

\func{bool}{RmDir}{\param{const wxString\&}{ dir}}

Remove the specified directory from the current FTP working directory.
Returns TRUE if successful.

\membersection{wxFTP::Pwd}

\func{wxString}{Pwd}{\void}

Returns the current FTP working directory.

% ----------------------------------------------------------------------------

\membersection{wxFTP::Rename}

\func{bool}{Rename}{\param{const wxString\&}{ src}, \param{const wxString\&}{ dst}}

Rename the specified \it{src} element to \it{dst}. Returns TRUE if successful.

% ----------------------------------------------------------------------------

\membersection{wxFTP::RmFile}

\func{bool}{RmFile}{\param{const wxString\&}{ path}}

Delete the file specified by \it{path}. Returns TRUE if successful.

% ----------------------------------------------------------------------------

\membersection{wxFTP::SetUser}

\func{void}{SetUser}{\param{const wxString\&}{ user}}

Sets the user name to be sent to the FTP server to be allowed to log in.

\wxheading{Default value}

The default value of the user name is "anonymous".

\wxheading{Remark}

This parameter can be included in a URL if you want to use the URL manager.
For example, you can use: "ftp://a\_user:a\_password@a.host:service/a\_directory/a\_file"
to specify a user and a password.

\membersection{wxFTP::SetPassword}

\func{void}{SetPassword}{\param{const wxString\&}{ passwd}}

Sets the password to be sent to the FTP server to be allowed to log in.

\wxheading{Default value}

The default value of the user name is your email address. For example, it could
be "username@userhost.domain". This password is built by getting the current
user name and the host name of the local machine from the system.

\wxheading{Remark}

This parameter can be included in a URL if you want to use the URL manager.
For example, you can use: "ftp://a\_user:a\_password@a.host:service/a\_directory/a\_file"
to specify a user and a password.

\membersection{wxFTP::GetList}

\func{wxList *}{GetList}{\param{const wxString\&}{ wildcard}}

The GetList function is quite low-level. It returns the list of the files in
the current directory. The list can be filtered using the \it{wildcard} string.
If \it{wildcard} is a NULL string, it will return all files in directory.

The form of the list can change from one peer system to another. For example,
for a UNIX peer system, it will look like this:

\begin{verbatim}
-r--r--r--   1 guilhem  lavaux      12738 Jan 16 20:17 cmndata.cpp
-r--r--r--   1 guilhem  lavaux      10866 Jan 24 16:41 config.cpp
-rw-rw-rw-   1 guilhem  lavaux      29967 Dec 21 19:17 cwlex_yy.c
-rw-rw-rw-   1 guilhem  lavaux      14342 Jan 22 19:51 cwy_tab.c
-r--r--r--   1 guilhem  lavaux      13890 Jan 29 19:18 date.cpp
-r--r--r--   1 guilhem  lavaux       3989 Feb  8 19:18 datstrm.cpp
\end{verbatim}

But on Windows system, it will look like this:

\begin{verbatim}
winamp~1 exe    520196 02-25-1999  19:28  winamp204.exe
        1 file(s)           520 196 bytes
\end{verbatim}

The list is a string list and one node corresponds to a line sent by the peer.

\membersection{wxFTP::GetOutputStream}

\func{wxOutputStream *}{GetOutputStream}{\param{const wxString\&}{ file}}

Initializes an output stream to the specified \it{file}. The returned
stream has all but the seek functionality of wxStreams. When the user finishes
writing data, he has to delete the stream to close it.

\wxheading{Return value}

An initialized write-only stream.

\helpref{wxOutputStream}{wxoutputstream}

\membersection{wxFTP::GetInputStream}\label{wxftpgetinput}

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

Creates a new input stream on the the specified path. You can use all but seek
functionnality of wxStream. Seek isn't available on all stream. For example,
http or ftp streams doesn't deal with it. Other functions like 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 NULL if an error occured (it could be a network failure or the fact
that the file doesn't exist).

Returns the initialized stream. You will have to delete it yourself once you
don't use it anymore. The destructor close the DATA stream connection but
will leave the COMMAND stream connection opened. It means that you still
can send new commands without reconnecting.

\wxheading{Example of a standalone connection (without wxURL)}

\begin{verbatim}
  wxFTP ftp;
  wxInputStream *in\_stream;
  char *data;

  ftp.Connect("a.host.domain");
  ftp.ChDir("a\_directory");
  in\_stream = ftp.GetInputStream("a\_file\_to\_get");

  data = new char[in\_stream->StreamSize()];

  in\_stream->Read(data, in\_stream->StreamSize());
  if (in\_stream->LastError() != wxStream\_NOERROR) {
    // Do something.
  }

  delete in\_stream; /* Close the DATA connection */

  ftp.Close(); /* Close the COMMAND connection */
\end{verbatim}
