sco_storage_v1.next_column

Catalogue snapshot — development preview

SDK 2.4.0 · game pack 0.8.0 · source d16f013c629797275e40124184b261da54cce0ef Published release: sdk-v2.4.0-rc.1 (release candidate 1, attested assets; the final signed release follows; this development preview is not an approved release). Source-backed inventory is not a runtime or in-game verification claim.

The column at declaration position inout_index of one own table or view (views report their result columns): name and declared type copy NUL-terminated with two size handshakes; out_flags gets the SCO_STORAGE_COLUMN_ bitmask (a column without a declared type gets “”). On success *inout_index advances to the next position. SCO_NOT_FOUND: no such object, or *inout_index is past the last column (outputs untouched). BAD_ARG: NULL inout pointers, malformed table name.

Limitations / unestablished guarantees

• Same-call recursive reentrancy unspecified.
• Additional failures/output state unspecified unless described in the buffer contract.

Parameters and buffers

sco_result (*next_column)(sco_plugin* self, const char* table, uint32_t* inout_index, char* name, uint32_t* name_size, char* type, uint32_t* type_size, uint32_t* out_flags);
The column at declaration position inout_index of one own table or view (views report their result columns): name and declared type copy NUL-terminated with two size handshakes; out_flags gets the SCO_STORAGE_COLUMN_ bitmask (a column without a declared type gets “”). On success *inout_index advances to the next position. SCO_NOT_FOUND: no such object, or *inout_index is past the last column (outputs untouched). BAD_ARG: NULL inout pointers, malformed table name.

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

Absent table: query_service NOT_FOUND.

Ownership

Caller buffers; inputs/SQL parameters copied during call. Host owns database/cursors; no SQLite pointer or allocation crosses the ABI.

Thread affinity

Any thread; calls serialize per plugin. Same-call recursive reentrancy unspecified.

Callback context

unspecified

Reentrancy

unspecified

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

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
