Device Driver Loader and Tux Extender

The Device Driver Loader and Tux Extender (DDLX), Ddlx.dll, is a set of tools that extend the capabilities of the Tux test harness. DDLX allows the dynamic-link library (DLL) for your test to operate in either an application or a Device.exe address space.

When using Tux alone, your test DLL loads into the address space for Tux. However, when using DDLX in combination with Tux, Ddlx.dll loads into the address space for Tux. Ddlx.dll registers your test DLL as a device driver in the Device.exe address space and provides an interface to your test DLL. This approach allows your test DLL to run in the Device.exe address space while also taking advantage of the features of Tux.

When your test DLL executes and returns values to DDLX, DDLX accepts the return codes and translates them into valid return codes for Tux. DDLX provides a way for Tux and your test DLL to communicate across different address spaces.
