de.gematik.smartcards.pcsc.lib.Dword
All Implemented Interfaces:
com.sun.jna.NativeMapped, Serializable
public class Dword extends com.sun.jna.IntegerType
The DWORD type used by WinSCard.h, used wherever an integer is needed in SCard functions.

On Windows and OS X, this is always typedef'd to an uint32_t. In the pcsclite library on Linux, it is a long instead, which is 64 bits on 64-bit Linux.
