Viewing the Demo Adaptor Source Files

This section describes a suggested order in which you should look at the demo adaptor

source files.

mwdemoimaq.h

A good place to start looking at the demo adaptor is to open the mwdemoimaq.h file.

This file defines the five functions that every adaptor must export. The toolbox engine

calls these functions to get information about supported hardware, instantiate a video

input object, and acquire data. Implementing these functions is typically the first step

an adaptor writer takes. This header file contains comments that explain the purpose of

each function.

mwdemoimaq.cpp

After seeing the definition of the adaptor exported functions, see how they are

implemented in the corresponding C++ implementation file, mwdemoimaq.cpp.
