sco_ui_surfaces_v1.last_error

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.

The message of this plugin’s last refused call (“” if none), NUL-terminated, with the raw-handler size handshake (*inout_size: capacity in; bytes written, or needed with TOO_MANY, out).

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 (*last_error)(sco_plugin* self, char* out, uint32_t* inout_size);
The message of this plugin’s last refused call (“” if none), NUL-terminated, with the raw-handler size handshake (*inout_size: capacity in; bytes written, or needed with TOO_MANY, out).

Results and failures

OK; TOO_MANY buffer too small (*inout_size = bytes needed); BAD_ARG invalid/released self, NULL inout_size or NULL out with nonzero capacity; UNAVAILABLE stopped service. Diagnostic completeness unspecified.

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

Caller-owned buffer written in place. 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 read. Unload and Stop clear the message.

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 (*last_error)
cpp	typed-wrapper	include/scosdk/ui_surfaces.hpp sco_result r = table_->last_error(self_, out.data(), &size);
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

None identified in the catalogue; this is not proof none can exist.
