ClearPages Method
Clears a range of pages in a page blob.
Syntax
azureblob.clearPages(pageBlob, byteOffset, pageCount, [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 clears PageCount pages, from ByteOffset onwards, for the specified PageBlob in the container currently selected by Container.
ByteOffset must be a multiple of 512; i.e. ByteOffset % 512 == 0. PageCount must be a number between 1 and the number of pages in the page blob following ByteOffset (inclusive).
If the specified blob has an active lease, its lease Id must be specified using LeaseId, or the request will fail.
