sco_datacore_v1.append

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.

Appends one element to an array field: a value, a pointer (SCO_DC_NULL, SCO_DC_INSTANCE), or for an array of structs SCO_DC_INSTANCE, the added instance to copy in.

Limitations / unestablished guarantees

• Internal allocation/failure guarantee unspecified.
• Recursive/concurrent same-patch reentrancy unspecified.
• Additional failures/output state unspecified unless described in the buffer contract.

Header source

Parameters and buffers

sco_result (*append)(uint64_t patch, const char* record, const char* field, const sco_dc_value* v);
Appends one element to an array field: a value, a pointer (SCO_DC_NULL, SCO_DC_INSTANCE), or for an array of structs SCO_DC_INSTANCE, the added instance to copy in.

Results and failures

Absent table: query_service NOT_FOUND; stopped operations: UNAVAILABLE. Unknown/released patch: NOT_FOUND; closed patch: BAD_ARG; operation cap: TOO_MANY. Additional failures/output state unspecified unless described in the buffer contract.

Absent capability

Absent table: query_service NOT_FOUND

Ownership

Strings/values copied; host owns patches and instances; IDs, not allocations, cross the ABI. Internal allocation/failure guarantee unspecified.

Thread affinity

Any thread; short locks, no wait for game load. Recursive/concurrent same-patch reentrancy unspecified.

Callback context

unspecified

Reentrancy

unspecified

Cleanup and cancellation

No in-flight cancellation; discard drops open/queued patch, not applied or saved effects. Unload forgets owned patches.

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_datacore.h (*append)
cpp	typed-wrapper	include/scosdk/datacore.hpp return appending_ ? t_->append(id_, rec.c_str(), f.c_str(), &v) : t_->set(id_, rec.c_str(), f.c_str(), &v);
csharp	typed-wrapper	sdk/csharp/Sco.Sdk/DataCore.cs return t->append(Id, r, f, v.Ptr);
lua	typed-wrapper	plugins/lua/sco_lua_game.c const sco_result r = dc->append(p->id, record, field, v.type == SCO_DC_NULL ? NULL : &v);
