Append Method

Append data from LocalFile to a RemoteFile on an FTP server.

Syntax

ftp.append([callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method causes the server-DTP to accept the data transferred via the data connection and to store the data in a file on the server site. If the file specified in the pathname exists on the server site, then the data shall be appended to that file; otherwise the file specified in the pathname shall be created on the server site. Similar to the Upload method but the local file specified by LocalFile is appended to RemoteFile on the server as opposed to replacing it as done by the Upload method. RemoteFile is either an absolute path on the server, or a path relative to RemotePath. The server will create a file with that name if it doesn't already exist (similar to Upload). If there is no FTP session in place, one is automatically created by first calling the Logon method.
