moduleExample.cpp

Example demonstrating how to load an ArModuleThis is a simple program that loads the module moduleExample_Mod, which is defined in moduleExample_Mod.cpp. The program simply calls ArModuleLoader::load() with a short message argument and ArModuleLoader::reload with no argument and finally calls ArModuleLoader::close(). The return status of the load(), reload(), and close() are checked and printed out. ArModuleLoader uses the name of the module file without the platform-specific suffix (i.e. ".dll" on Windows and ".so" on Linux) to load the module.
