XrHandJointLocationsEXT to get hand tracking data source state.
XrHandTrackingDataSourceStateEXT is a structure that an application can chain to XrHandJointLocationsEXT::next when calling LocateHandJointsEXT to retrieve the data source of the currently active hand tracking device.
When the returned isActive is XR_FALSE, it indicates the currently active hand tracking device does not support any of the requested data sources. In these cases, the runtime must also return no valid tracking locations for hand joints from this LocateHandJointsEXT function.
If the tracker was not created with XrHandTrackingDataSourceInfoEXT chained to XrHandTrackerCreateInfoEXT::next, then the runtime must return ERROR_VALIDATION_FAILURE, if XrHandTrackingDataSourceStateEXT is passed in the call to LocateHandJointsEXT.
If there is an active hand tracking device that is one of the specified requestedDataSources, the runtime must set isActive to TRUE. When the runtime sets isActive to TRUE, the runtime must set dataSource indicate the active data source. The runtime must return a dataSource that is a subset of the requestedDataSources when creating the corresponding hand tracker.
XR_EXT_hand_tracking_data_source extension must be enabled prior to using XrHandTrackingDataSourceStateEXTtype must be TYPE_HAND_TRACKING_DATA_SOURCE_STATE_EXTnext must be NULL or a valid pointer to the next structure in a structure chaindataSource must be a valid XrHandTrackingDataSourceEXT valueXrHandJointLocationsEXT, LocateHandJointsEXT
