sc_entities_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 reason for self’s last failed call (“” if none), NUL-terminated, with the size handshake (*inout_size: capacity in; bytes written, or needed with SCO_TOO_MANY, out). self NULL: the last failure of a call made without a plugin handle (alive’s neighbours: class_of, get_transform, query_radius). Any thread.

Limitations / unestablished guarantees

• Internal allocation unspecified.
• recursive reentrancy unspecified.
• stopped-service refusal unspecified (no started check).
• Game-service behavior not verified in a game session.

Header source

Parameters and buffers

sco_result (*last_error)(sco_plugin* self, char* out, uint32_t* inout_size);
The reason for self’s last failed call (“” if none), NUL-terminated, with the size handshake (*inout_size: capacity in; bytes written, or needed with SCO_TOO_MANY, out). self NULL: the last failure of a call made without a plugin handle (alive’s neighbours: class_of, get_transform, query_radius). Any thread.

Results and failures

BAD_ARG invalid/released non-NULL self or buffer; TOO_MANY required bytes. NULL self selects no-self failures; stopped-service refusal unspecified (no started check).

Absent capability

unspecified

Ownership

Caller buffers; no allocation crosses boundary. Host owns entity/watch tracking; IDs are session values. Internal allocation unspecified.

Thread affinity

Any thread; diagnostic scope as described; recursive reentrancy unspecified.

Callback context

unspecified

Reentrancy

unspecified

Cleanup and cancellation

No in-flight cancellation entrypoint; owned entities removed and watches ended on ordinary unload/non-retained crash cleanup, except kept entities. Retained-provider faults skip owner resource-release hooks and require restart; backing resources remain retained, not safe for cached calls.

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/sc_entities.h (*last_error)
cpp	typed-wrapper	include/scosdk/game/entities.hpp sco_result r = t_->last_error(who, s.data(), &size);
csharp	typed-wrapper	sdk/csharp/Sco.Sdk/Game/Entities.cs return Storage.Sized((buf, size) => ((ScEntitiesV1*)t)->last_error((void*)who, buf, size), out byte[] b) == ScoResult.Ok
lua	restricted	plugins/lua/sco_lua_game.c if (GAME_MEMBER(e, sc_entities_v1, last_error) && e->last_error(NULL, msg, &size) == SCO_OK && msg[0]) { lua_pushstring(L, msg); return 3; }
