Typedefs

ArResolveAnchorOnRooftopCallback

void(* ArResolveAnchorOnRooftopCallback)(void *context, ArAnchor *anchor, ArRooftopAnchorState rooftop_anchor_state)

Callback definition for ArEarth_resolveAnchorOnRooftopAsync .

The context argument will be the same as that passed to ArEarth_resolveAnchorOnRooftopAsync . The anchor argument will be the same as that returned by ArResolveAnchorOnRooftopFuture_acquireResultAnchor and must be released using ArAnchor_release . The rooftop_anchor_state argument will be the same as that returned by ArResolveAnchorOnRooftopFuture_getResultRooftopAnchorState .

It is a best practice to free context memory provided to ArEarth_resolveAnchorOnRooftopAsync at the end of the callback implementation.

ArResolveAnchorOnRooftopFuture

struct ArResolveAnchorOnRooftopFuture_ ArResolveAnchorOnRooftopFuture

Handle to an asynchronous operation launched by ArEarth_resolveAnchorOnRooftopAsync .

Release with ArFuture_release . ( reference type, long-lived ).

Functions

ArResolveAnchorOnRooftopFuture_acquireResultAnchor

 void 
  
 ArResolveAnchorOnRooftopFuture_acquireResultAnchor 
 ( 
  
 const

  ArResolveAnchorOnRooftopFuture

 out_anchor 
 )

Gets the resolved Rooftop anchor.

If the operation isn't done yet or the operation failed, this will be NULL . The caller must release the anchor using ArAnchor_release .
