KSPROPERTY_CAMERACONTROL_NODE_S2 structure

The KSPROPERTY_CAMERACONTROL_NODE_S2 structure describes node-based properties in the PROPSETID_VIDCAP_CAMERACONTROL property set that use two values at the same time. This structure specifies property values in requests to the USB video class driver.

Syntax


typedef struct {
  KSP_NODE NodeProperty;
  LONG     Value1;
  ULONG    Flags;
  ULONG    Capabilities;
  LONG     Value2;
} KSPROPERTY_CAMERACONTROL_NODE_S2, *PKSPROPERTY_CAMERACONTROL_NODE_S2;
