Parameters

ioControlCode: IIOControlCode

The IO control code.

inputBuffer: IBuffer

The input buffer.

outputBuffer: IBuffer

The output buffer.

Returns

IAsyncOperation<Boolean>

Remarks

TrySendIOControlAsync is like SendIOControlAsync, except this method doesn't throw an exception if the operation fails. Instead, it returns false. If you want to handle any exceptions that occur during the operation, use the SendIOControlAsync method.
