sco_ipc_v1.peer_age_ms

Milliseconds since the peer’s last beat (capped at UINT32_MAX). SCO_NOT_FOUND: no such channel, or the peer hasn’t beaten yet (*out_ms 0).

Signature

Header source

Parameters and buffers

sco_result (*peer_age_ms)(sco_plugin* self, uint64_t channel, uint32_t* out_ms);
Milliseconds since the peer’s last beat (capped at UINT32_MAX). SCO_NOT_FOUND: no such channel, or the peer hasn’t beaten yet (*out_ms 0).

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.

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