Parameters and buffers
Section titled “Parameters and buffers”sco_result (*del)(sco_plugin* self, const char* key);
Removes a key. SCO_NOT_FOUND: there was none.
Results and failures
Section titled “Results and failures”Absent table: query_service NOT_FOUND. Stopped: UNAVAILABLE; invalid/released self: BAD_ARG. Allocation exceptions: TOO_MANY; database errors may be FAILED. Additional failures/output state unspecified unless described in the buffer contract.
Absent capability
Section titled “Absent capability”Absent table: query_service NOT_FOUND.
Ownership
Section titled “Ownership”Caller buffers; inputs/SQL parameters copied during call. Host owns database/cursors; no SQLite pointer or allocation crosses the ABI.
Thread affinity
Section titled “Thread affinity”Any thread; calls serialize per plugin. Same-call recursive reentrancy unspecified.
Callback context
Section titled “Callback context”unspecified
Reentrancy
Section titled “Reentrancy”unspecified
Cleanup and cancellation
Section titled “Cleanup and cancellation”No cancellation entrypoint; ordinary unload/non-retained crash cleanup rolls back transaction and closes cursors/database. Retained-provider faults skip owner resource-release hooks and require restart; backing resources remain retained, not safe for cached calls.
Language mappings
Section titled “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.
