What is PROPERTY_VALUE_INVALID

PROPERTY_VALUE_INVALID is mentioned in the SDK Documentation a couple times, for example in the page for QueryDepthLowConfidenceValue. However,

if (device->QueryDepthLowConfidenceValue() == PROPERTY_VALUE_INVALID)

reports an error that PROPERTY_VALUE_INVALID is undefined.

Where did you get that property?, I can't find it, so I would agree with the compiler...

It is not defined here at least (try searching for it):

I'm looking in the documentation that came with the SDK when I installed it:

"C:\Program Files (x86)\Intel\RSSDK\doc\CHM\sdkhelp.chm"

There are 47 references to PROPERTY_VALUE_INVALID.

The docs that come with the SDK say things like (in QueryDepthUnit):

Return Status

The native depth pixel precision in micrometers or μm, or PROPERTY_VALUE_INVALID if there is any error in retrieving the value.

While the web version says only

Return Status

The native depth pixel precision in micrometers or μm.

I take it things have been updated?

It seems that the windows documentation is out of sync with the sources.

Basically, that property does not currently exist.

So is there any way that these functions can report an error?
