Clarify xrEnumerateInstanceExtensionProperties for API layers

Open fredemmott opened this issue 1 year ago • 3 comments

Per https://registry.khronos.org/OpenXR/specs/1.1/html/xrspec.html#api-initialization , this function can be called before calling xrCreateInstance.

This function may: be called before an instance has been created; implementations must: not assume an instance exists.

Concretely, a bug in past versions of the Ultraleap API layer crashed if an instance had not been created.

I think this is a good clarification. I'd be happy for this to be merged.
