Marshal

View source
imguicpp.Marshal (Class)

cpp-target scratch storage used by the generated portable facade (imgui.ImGui). All scratch lives in unmanaged (malloc'd) memory so no hxcpp GC interaction can ever invalidate a pointer mid-call, and nothing here allocates garbage per frame.

NOT thread-safe - but neither is Dear ImGui (single context, main thread).

strScratch(s: String, maxLength: Int): cpp.Star

Copy the UTF-8 bytes of s (clamped to maxLength BYTES, on a codepoint boundary) into the scratch buffer and return it, zero-terminated.
