If you want to reverse engineer the file omreactive.cpp, it has the following included files:
#include <oxf.h>
#include <omoutput.h>
#include <omreactive.h>
#include <state.h>
#include <omthread.h>
#include <aommacro.h>
If you specified all these files except for state.h, all the include files except for state.h will be analyzed by the reverse engineering tool.
