DIDRIVERVERSIONS structure (dinputd.h)

  • Article

The DIDRIVERVERSIONS structure is used by the DirectInput effect driver to report version information back to DirectInput. The semantics of the version numbers are left to the discretion of the device driver. The only requirement is that later versions have higher version numbers than earlier versions.

Syntax

typedef struct DIDRIVERVERSIONS {
  DWORD dwSize;
  DWORD dwFirmwareRevision;
  DWORD dwHardwareRevision;
  DWORD dwFFDriverVersion;
} DIDRIVERVERSIONS, *LPDIDRIVERVERSIONS;

Members

dwSize

dwFirmwareRevision

Specifies the firmware revision of the device.

dwHardwareRevision

Specifies the hardware revision of the device.
