This keyword is not expanded by Git which means it's not replaced with the correct revision value in the releases made using git-based scripts and it's confusing to have lines with unexpanded "$Id$" in the released files. As expanding them with Git is not that simple (it could be done with git archive and export-subst attribute) and there are not many benefits in having them in the first place, just remove all these lines. If nothing else, this will make an eventual transition to Git simpler. Closes #14487. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@74602 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

@class wxFTP
|
|
|
|
wxFTP can be used to establish a connection to an FTP server and perform all the
|
|
usual operations. Please consult the RFC 959 (http://www.w3.org/Protocols/rfc959/)
|
|
for more details about the FTP protocol.
|
|
|
|
wxFTP can thus be used to create a (basic) FTP @b client.
|
|
|
|
To use a command which doesn't involve file transfer (i.e. directory oriented
|
|
commands) you just need to call a corresponding member function or use the
|
|
generic wxFTP::SendCommand() method.
|
|
However to actually transfer files you just get or give a stream to or from this
|
|
class and the actual data are read or written using the usual stream methods.
|
|
|
|
Example of using wxFTP for file downloading:
|
|
|
|
@code
|
|
wxFTP ftp;
|
|
|
|
// if you don't use these lines anonymous login will be used
|
|
ftp.SetUser("user");
|
|
ftp.SetPassword("password");
|
|
|
|
if ( !ftp.Connect("ftp.wxwidgets.org") )
|
|
{
|
|
wxLogError("Couldn't connect");
|
|
return;
|
|
}
|
|
|
|
ftp.ChDir("/pub/2.8.9");
|
|
const char *filename = "wxWidgets-2.8.9.tar.bz2";
|
|
int size = ftp.GetFileSize(filename);
|
|
if ( size == -1 )
|
|
{
|
|
wxLogError("Couldn't get the file size for \"%s\"", filename);
|
|
}
|
|
|
|
wxInputStream *in = ftp.GetInputStream(filename);
|
|
if ( !in )
|
|
{
|
|
wxLogError("Couldn't get the file");
|
|
}
|
|
else
|
|
{
|
|
char *data = new char[size];
|
|
if ( !in->Read(data, size) )
|
|
{
|
|
wxLogError("Read error: %d", ftp.GetError());
|
|
}
|
|
else
|
|
{
|
|
// file data is in the buffer
|
|
...
|
|
}
|
|
|
|
delete [] data;
|
|
delete in;
|
|
}
|
|
|
|
// gracefully close the connection to the server
|
|
ftp.Close();
|
|
@endcode
|
|
|
|
To upload a file you would do (assuming the connection to the server was opened
|
|
successfully):
|
|
|
|
@code
|
|
wxOutputStream *out = ftp.GetOutputStream("filename");
|
|
if ( out )
|
|
{
|
|
out->Write(...); // your data
|
|
delete out;
|
|
}
|
|
@endcode
