示例1: WriteData
private bool WriteData(byte[] data, int timeout)
{
if (_deviceCapabilities.OutputReportByteLength <= 0) return false;
var buffer = CreateOutputBuffer();
uint bytesWritten = 0;
Array.Copy(data, 0, buffer, 0, Math.Min(data.Length, _deviceCapabilities.OutputReportByteLength));
if (_deviceWriteMode == DeviceMode.Overlapped)
{
var security = new NativeMethods.SECURITY_ATTRIBUTES();
var overlapped = new NativeOverlapped();
var overlapTimeout = timeout <= 0 ? NativeMethods.WAIT_INFINITE : timeout;
security.lpSecurityDescriptor = IntPtr.Zero;
