uxctl.dll

Source	src/uxctl/
CMake target	uxctl
Type	Win32 DLL
Family	DirectUI engine layer

At a glance

A small control-host DLL for the DirectUI stack — the process-level init/uninit and object-creation entry points that a DirectUI host calls before using controls. In the original architecture it pairs with uxcore.dll (see UXCore).

Public surface

From uxctl.def:

UxControlsInitProcess
UxControlsCreateObject
UxControlsUninitProcess

All __stdcall.

Implementation notes

• UxControlsInitProcess sets up per-process control state; UxControlsUninitProcess tears it down; UxControlsCreateObject is the class-factory-style creation entry.
• Like wlidcli, this DLL is among the delay-loaded optional components on some original setups — the engine survives its absence (Quirk #11).
• Links: kernel32, user32, gdi32, advapi32, ole32, ... (system libs only).

Testing

• Export-parity and decoration contracts in tests/mmr-python.
