sco_widgets_v1.remove_nodes

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.

Atomically removes 1..256 listed nodes of an owned panel, each with its subtree. Every ID must be nonzero and present; a removal that would empty the panel is refused (use remove_panel). The ID array is read during the call only. Failure preserves the tree.

Limitations / unestablished guarantees

• No scosdk C++ wrapper, C# or Lua route for the 1.1 members yet; C and C++ call the table directly.
• Headless host tests only; not run in game. Renderer presentation of severity, tooltips and paging is the host adapter’s.

Parameters and buffers

sco_result (*remove_nodes)(sco_plugin* self, const char* panel_id, const uint32_t* node_ids, uint32_t count);
Atomically removes 1..256 listed nodes of an owned panel, each with its subtree. Every ID must be nonzero and present; a removal that would empty the panel is refused (use remove_panel). The ID array is read during the call only. Failure preserves the tree.

Results and failures

OK; WRONG_THREAD off game thread; UNAVAILABLE stopped service/host; BAD_ARG invalid owner/ID, NULL or empty array, zero ID or emptied panel; NOT_FOUND absent owned panel or node ID; TOO_MANY more than 256 IDs. Failure atomic.

Absent capability

Check the table size covers the member and the pointer is non-NULL: a 1.0 table (24 bytes) has no 1.1 members. query_service answers UNAVAILABLE for 1.1 against a 1.0 host.

Ownership

Host releases the removed copies; caller keeps the ID array. fn/ctx unchanged. No allocation transfer.

Thread affinity

Game thread only; WRONG_THREAD elsewhere. Callbacks game thread under owner callout guard.

Callback context

Event, text and panel ID borrowed during callback only; callback ctx is plugin-owned.

Reentrancy

Callable from the panel’s own event callback; generation change drops remaining stale events, new tree renders next pass. Registry lock not held during plugin code.

Cleanup and cancellation

Success starts a new generation: remaining events of the current pass drop and the change renders next pass. Owner release and fault rules as set_panel. No separate cancel token.

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_widgets.h (*remove_nodes)
cpp	direct	include/sco_widgets.h (*remove_nodes)
csharp	unsupported	docs/contracts.md C# and Lua sco.widgets 1.1 routes are unsupported.
lua	unsupported	docs/contracts.md C# and Lua sco.widgets 1.1 routes are unsupported.

Examples
