sc_container_contents_v1.snapshot

Copy at most 64 stored-item records for a session-local container into caller-owned storage; count is capacity in and copied count out, total_seen reports omitted items and generation identifies the provider snapshot. Quantity is positive; volume is meaningful only with VOLUME_KNOWN. No engine pointers or mutation cross the ABI.

Parameters and buffers

sco_result (*snapshot)(sco_plugin* self, uint64_t container_id, sc_container_snapshot* out);
Copy at most 64 stored-item records for a session-local container into caller-owned storage; count is capacity in and copied count out, total_seen reports omitted items and generation identifies the provider snapshot. Quantity is positive; volume is meaningful only with VOLUME_KNOWN. No engine pointers or mutation cross the ABI.

Results and failures

OK snapshot; BAD_ARG invalid handle, id, output size or capacity; WRONG_THREAD off game thread; NOT_FOUND unknown container; UNAVAILABLE unbound or stopping; FAILED malformed provider or exception. Known output prefix is cleared on failure, future caller tail untouched.

Absent capability

game.inventory.contents.read defaults OFF; no native engine adapter. Synthetic evidence only, not run in game.

Ownership

Caller owns output; provider receives service-owned scratch storage only. IDs are session-local, no pointers retained.

Thread affinity

Game thread only.

Callback context

No plugin callback.

Reentrancy

Recursive provider reads fail with FAILED.

Cleanup and cancellation

Service stop withdraws table and drops host-owned backend references. Read-only, no engine state to restore.

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_container_contents.h `(*snapshot)`
cpp	typed-wrapper	include/scosdk/game/container_contents.hpp `table_->snapshot(owner_, container, &out)`

Examples

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

Tests

Find by task

read container contents; list stored items in a container

This is a search phrase for the existing contract, not an additional API alias.

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