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 the getDirSummaryNameQuota([callback]) method is defined as:

function(err, data){ }

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

'data' is the value returned by the method.

The callback for the setDirSummaryNameQuota([callback]) 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

The name quota imposed on the directory.

This property reflects the name quota imposed on the directory, or -1 if the directory doesn't have a name quota set.

A name quota limits the number of files and directories that can be created within a directory (calculated recursively). Note that a directory's own name is counted against its own quota, so the minimum name quota that may be applied to a directory is 1 (which will force the directory to stay empty).

This property is read-only and not available at design time.
