azureblob.appendBlock(appendBlob, [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 appends a block of data to the specified AppendBlob in the container currently selected by Container. The block of data is immediately available as part of the append blob, which must already exist.
Up to 4MB (4194304 bytes) of data may be appended in a single block, and up to 50000 blocks may be appended to a single append blob.
If the specified blob has an active lease, its lease Id must be specified using LeaseId, or the request will fail.
