sco_ipc_v1.ring_push

Appends one record to the SCO_IPC_TO_PEER ring at offset. SCO_TOO_MANY: full now. SCO_NOT_FOUND: no ring laid out there. SCO_BAD_ARG: a FROM_PEER ring, type 0xFFFFFFFF, or a record the ring can never hold.

Parameters and buffers

sco_result (*ring_push)(sco_plugin* self, uint64_t channel, uint64_t offset, uint32_t type, const void* data, uint32_t size);
Appends one record to the SCO_IPC_TO_PEER ring at offset. SCO_TOO_MANY: full now. SCO_NOT_FOUND: no ring laid out there. SCO_BAD_ARG: a FROM_PEER ring, type 0xFFFFFFFF, or a record the ring can never hold.

Results and failures

Absent table: query_service NOT_FOUND; stopped: UNAVAILABLE; invalid/released self: BAD_ARG; unknown/non-owned channel: NOT_FOUND; allocation exceptions: TOO_MANY. Additional failures/output state unspecified unless described in the buffer contract.

Absent capability

Absent table: query_service NOT_FOUND

Ownership

Host owns mapping/channel; data copied via host staging buffers. No allocation transfer except borrowed view, never free it.

Thread affinity

Any thread; per-channel lock during copy. Recursive reentrancy unspecified.

Callback context

unspecified

Reentrancy

unspecified

Cleanup and cancellation

No in-flight cancellation; close/ordinary unload/non-retained crash cleanup marks closed and unmaps channels. 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
c	direct	include/sco_ipc.h `(*ring_push)`
cpp	typed-wrapper	include/scosdk/ipc.hpp `return t_->ring_push(self_, id_, offset, type, data.data(), static_cast<uint32_t>(data.size()));`
csharp	unsupported	docs/sdk-csharp.md `There are no C# wrappers for sco.ipc and sco.net yet`
lua	unsupported	docs/ipc.md `Lua plugins get no sco.ipc`

Examples

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

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