sco_widgets_v1.capabilities

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.

caps[0] is the array length on entry (at least 2) and the number of elements written on success; the host fills the SCO_WIDGETS_CAP_* indices it knows up to that length: feature bits, then the running limits for panels, nodes/panel, live nodes, items, columns, text bytes and events per pass. 1.1 defines 9 elements. Failure writes nothing.

Limitations / unestablished guarantees

• No scosdk C++ wrapper, C# or Lua route for the 1.1 members yet; C and C++ call the table directly.
• Headless host tests only; not run in game. Renderer presentation of severity, tooltips and paging is the host adapter’s.

Parameters and buffers

sco_result (*capabilities)(sco_plugin* self, uint32_t* caps);
caps[0] is the array length on entry (at least 2) and the number of elements written on success; the host fills the SCO_WIDGETS_CAP_* indices it knows up to that length: feature bits, then the running limits for panels, nodes/panel, live nodes, items, columns, text bytes and events per pass. 1.1 defines 9 elements. Failure writes nothing.

Results and failures

OK; WRONG_THREAD off game thread; UNAVAILABLE stopped service/host; BAD_ARG invalid/released owner, NULL caps or caps[0] below 2.

Absent capability

Check the table size covers the member and the pointer is non-NULL: a 1.0 table (24 bytes) has no 1.1 members. query_service answers UNAVAILABLE for 1.1 against a 1.0 host.

Ownership

Caller-owned array written in place. No allocation transfer.

Thread affinity

Game thread only; WRONG_THREAD elsewhere. No callbacks.

Callback context

No plugin callback.

Reentrancy

Callable from an event callback; reads constants under the registry lock, never held during plugin code.

Cleanup and cancellation

Synchronous query; nothing to release. No cancellation entrypoint.

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_widgets.h (*capabilities)
cpp	direct	include/sco_widgets.h (*capabilities)
csharp	unsupported	docs/contracts.md C# and Lua sco.widgets 1.1 routes are unsupported.
lua	unsupported	docs/contracts.md C# and Lua sco.widgets 1.1 routes are unsupported.

Examples

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

Tests

ABI pins prove layout, not semantic behavior or a live game session.
