556 @param valueCaps Points to a caller-allocated buffer that will contain, on return, an array of HIDValueCaps structures that contain information for all values that meet the search criteria.
672 @discussion The HIDGetUsageValue function does not sign the value. To have the sign bit automatically applied, use the HIDGetScaledUsageValue function instead. For manually assigning the sign bit, the position of the sign bit can be found in the HIDValueCaps structure for this value. Clients who wish to obtain all data for a usage that contains multiple data items for a single usage, corresponding to a HID byte array, must call the HIDGetUsageValueArray function instead.
703 @param usageValueBuffer Points to a caller-allocated buffer that contains, on output, the data from the device. The correct length for this buffer can be found by multiplying the reportCount and bitSize fields of the HIDValueCaps structure for the value and rounding the resulting value up to the nearest byte.
728 @param valueCaps On return, points to a caller-allocated buffer that contains an array of HIDValueCaps structures containing information for all values in the top level collection.
836 @discussion The HIDSetUsageVlaue function does not automatically handle the sign bit. Clients must either manually set the sign bit, at the position provided in the HIDValueCaps structure for this value, or call the HIDSetScaledUsageValue function.
