SupportODXReadWrite Property
Whether the virtual filesystem supports ODX (Offloaded Data Transfer) operations.
Syntax
cbfs.getSupportODXReadWrite([callback]) cbfs.setSupportODXReadWrite( supportODXReadWrite, [callback])
Default Value
FALSE
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 getSupportODXReadWrite([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 setSupportODXReadWrite([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
This property specifies whether the virtual filesystem should indicate to the system that it supports ODX (Offloaded Data Transfer) operations. Please refer to Microsoft's Offloaded Data Transfer article for more information.
If this property is enabled, the application must properly handle the OffloadReadFile and OffloadWriteFile events, which will fire anytime the OS sends an offload read or offload write request to the virtual filesystem.
Note: This property cannot be changed when Active is true, and cannot be changed within events.
This property is not available at design time.
