sco_ui_surfaces_v1.update_surface_pose

Catalogue snapshot — development preview

SDK 2.3.0 · game pack 0.6.0 · source e616ed69d8f9f77b0f4827881c86d91e4a7d1689 Published release: sdk-v2.3.0 (immutable approved assets; this development preview is not an approved release). Source-backed inventory is not a runtime or in-game verification claim.

Replaces the pose and panel of one of the caller’s surfaces, checked against the kind it was registered with (the register_surface rules). Failure leaves the old pose.

Limitations / unestablished guarantees

• Headless host tests only: no renderer projects or draws surfaces in sco-core, and nothing has run in a game.
• The panel shown is a sco.widgets panel id; the host checks its form and ownership, not that the panel exists.
• C# and Lua bindings are unsupported in 1.0.

Header source

Parameters and buffers

sco_result (*update_surface_pose)(sco_plugin* self, uint32_t id, const sco_surface_pose* pose);
Replaces the pose and panel of one of the caller’s surfaces, checked against the kind it was registered with (the register_surface rules). Failure leaves the old pose.

Results and failures

OK; NOT_FOUND no surface of this plugin by that id; BAD_ARG invalid/released self, NULL or short pose, any field outside the rules for the kind; TOO_MANY allocation failure; UNAVAILABLE stopped service.

Absent capability

query_service NOT_FOUND when the host does not publish sco.ui.surfaces (it needs sco.ui started); UNAVAILABLE for an incompatible version. No game capability or renderer requirement.

Ownership

Host copies the pose and panel_id on success; caller keeps pose and the string. No allocation transfer.

Thread affinity

Any thread; registry lock held only for the copy. No callbacks.

Callback context

No callbacks; desc, pose and panel_id are read during the call only.

Reentrancy

No plugin code runs inside the service; calls from several threads are serialized by the registry lock.

Cleanup and cancellation

No cancellation entrypoint; synchronous. The surface keeps its id and kind; unload, crash and Stop withdraw it.

Language mappings

Status labels are copied verbatim from the catalogue: direct is native access; typed-wrapper is wrapper-backed; restricted is a subset/adaptation; unsupported means no supported route is established. No status implies universal safety.

Language	Catalogue status	Source evidence / wrapper tokens
c	direct	include/sco_ui_surfaces.h (*update_surface_pose)
cpp	typed-wrapper	include/scosdk/ui_surfaces.hpp return table_->update_surface_pose(self_, id, &pose);
csharp	unsupported	docs/contracts.md C# and Lua sco.ui.surfaces routes are unsupported.
lua	unsupported	docs/contracts.md C# and Lua sco.ui.surfaces routes are unsupported.

Examples
