IOCTL_DISK_IS_WRITABLE IOCTL (winioctl.h)

确定指定的磁盘是否可写。

若要执行此操作，请使用以下参数调用 DeviceIoControl 函数。

BOOL DeviceIoControl(
  (HANDLE) hDevice,             // handle to device
  IOCTL_DISK_IS_WRITABLE,       // dwIoControlCode
  NULL,                         // lpInBuffer
  0,                            // nInBufferSize
  NULL,                         // lpOutBuffer
  0,                            // nOutBufferSize
  (LPDWORD) lpBytesReturned,    // number of bytes returned
  (LPOVERLAPPED) lpOverlapped   // OVERLAPPED structure
);
