IOCTL_DISK_IS_WRITABLE IOCTL (winioctl.h)

判斷指定的磁碟是否可寫入。

若要執行這項作業，請使用下列參數呼叫 DeviceIoControl 函式。

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
);
