Recover pointer results in the Mac word-wrap allocator and list builder

checked · by eejitgames · submitted 2026-11-06

Mac AllocWordWrapNode and WordWrapString still declare undefined results, while native code returns and consumes full heap-node pointers. The allocator returns its 8-byte node; the wrapper returns that node directly or the linked-list head. Allocation, linking, drawing and freeing agree on text pointer+0 and next pointer+4. Windows's allocator already returns D2TextLineStrc*. That struct is absent in Mac and propose cannot create structs, so use void* as the opaque node-pointer result. Preserve all existing inputs and calling conventions.
