Article

The DIOBJECTATTRIBUTES structure describes the information contained in the "Attributes" value of the registry key for each "object" on a device. If the "Attributes" value is absent, then default attributes are used.

Syntax

typedef struct DIOBJECTATTRIBUTES {
  DWORD dwFlags;
  WORD  wUsagePage;
  WORD  wUsage;
} DIOBJECTATTRIBUTES, *LPDIOBJECTATTRIBUTES;

Members

dwFlags

There may be zero, one, or more of the following flags:

DIDOI_FFACTUATOR

Indicates that the object can have force feedback effects applied to it.

DIDOI_FFEFFECTTRIGGER

Indicates that the object can trigger playback of force feedback effects.

DIDOI_ASPECTPOSITION

Indicates that the object reports position information.

DIDOI_ASPECTVELOCITY

Indicates that the object reports velocity information.

DIDOI_ASPECTACCEL

Indicates that the object reports acceleration information.

DIDOI_ASPECTFORCE

Indicates that the object reports force information.

DIDOI_ASPECTMASK

Indicates the bits that are used to report aspect information. An object can represent, at most, one aspect.

DIDOI_POLLED
