Parameters and buffers

sco_result (*unregister_overlay)(sco_plugin* self, const char* id);
SCO_NOT_FOUND: this plugin has no overlay by that id.

Results and failures

Absent capability

Absent table: query_service NOT_FOUND

Ownership

Removes own overlay. Free ctx immediately on game thread, including inside draw; elsewhere defer freeing via run_on_game_thread.

Thread affinity

Any thread; allowed inside own draw. Other reentrancy unspecified.

Callback context

unspecified

Reentrancy

allowed inside own draw.

Cleanup and cancellation

No in-flight cancellation API; unregister/unbind removes registration; ordinary unload/non-retained crash cleanup withdraws all UI. Retained-provider faults skip owner resource-release hooks and require restart; backing resources remain retained, not safe for cached calls. Guarded draws stop, but snapshots and chord reservations remain.

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_ui.h (*unregister_overlay)
cpp	typed-wrapper	include/scosdk/ui.hpp sco_result RemoveOverlay(const char* id) noexcept { return detail::CanCall(t_, &sco_ui_v1::unregister_overlay) ? t_->unregister_overlay(self_, id) : SCO_UNAVAILABLE; }
csharp	typed-wrapper	sdk/csharp/Sco.Sdk/Ui.cs fixed (byte* i = Utf8.Z(id)) r = _t->unregister_overlay(Self, i);
lua	unsupported	docs/ui.md Scripts bind hotkeys; tabs and overlays need draw callbacks from Lua
