Windows Driver Kit DDI reference (nf-wificx-wifirequestsetbytesneeded)

Description

WiFiCx drivers call the WifiRequestSetBytesNeeded function to set a larger buffer size for a command message.

Parameters

`Request`

[_In_] A handle to the framework request object passed in from the EvtWifiDeviceSendCommand callback function.

`BytesNeeded`

[_In_] The number of bytes needed.

Remarks

If WiFiCx sends a set command to the client driver's EvtWifiDeviceSendCommand callback function and the request doesn't contain a large enough buffer, the driver should call WifiRequestSetBytesNeeded to set the required buffer size and then fail the request with status BUFFER_OVERFLOW.
