WifiRequestSetBytesNeeded function (wificx.h)
WiFiCx drivers call the WifiRequestSetBytesNeeded function to set a larger buffer size for a command message.
Syntax
void WifiRequestSetBytesNeeded(
WIFIREQUEST Request,
UINT BytesNeeded
);
Parameters
Request
[In] A handle to the framework request object passed in from the EvtWifiDeviceSendCommand callback function.
BytesNeeded
[In] The number of bytes needed.
Return value
None
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.
