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.
