enums

I have a third-party (Win32) DLL, written in C, that exposes the following interface:

DLL_EXPORT typedef enum
{
  DEVICE_PCI = 1,
  DEVICE_USB = 2
} DeviceType;

DLL_EXPORT int DeviceStatus(DeviceType kind);

I wish to call it from Delphi.

How do I get access to the DeviceType constants in my Delphi code? Or, if I should just use the values 1 and 2 directly, what Delphi type should I use for the "DeviceType kind" parameters? Integer? Word?
