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 ArSession *session, const ArResolveAnchorOnRooftopFuture *future, ArAnchor **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
.
