@class wxFTP
@headerfile ftp.h wx/protocol/ftp.h
wxFTP can be used to establish a connection to an FTP server and perform all the
usual operations. Please consult the RFC 959 for more details about the FTP
protocol.
To use a commands 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.wxwindows.org") )
{
wxLogError("Couldn't connect");
return;
}
ftp.ChDir("/pub");
wxInputStream *in = ftp.GetInputStream("wxWidgets-4.2.0.tar.gz");
if ( !in )
{
wxLogError("Coudln't get file");
}
else
{
size_t size = in-GetSize();
char *data = new char[size];
if ( !in-Read(data, size) )
{
wxLogError("Read error");
}
else
{
// file data is in the buffer
...
}
delete [] data;
delete in;
}
@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
