sco_storage_v1.column

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.

Column index of the current row. out gets the type and value; TEXT and BLOB bytes go to buf with the size handshake (TEXT NUL-terminated; inout_size NULL: no bytes wanted). SCO_BAD_ARG: no current row, or index out of range.

Limitations / unestablished guarantees

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

Parameters and buffers

sco_result (*column)(sco_plugin* self, uint64_t cursor, uint32_t index, sco_sql_value* out, void* buf, uint32_t* inout_size);
Column index of the current row. out gets the type and value; TEXT and BLOB bytes go to buf with the size handshake (TEXT NUL-terminated; inout_size NULL: no bytes wanted). SCO_BAD_ARG: no current row, or index out of range.

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 owns descriptor and byte buffer. TEXT/BLOB descriptor v.p is NULL; numeric values copied. Host may allocate staging text.

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.
