Dear All,
What is the meaning of following declaration?
[code]
#ifndef __FPS_CONFIGURATION_PROJECT_CDF_
#define __FPS_CONFIGURATION_PROJECT_CDF_
[\code]

It defines the macro name __FPS_CONFIGURATION_PROJECT_CDF_ if it has not already been defined. It looks like possibly part of a header inclusion guard.
Incidentally, note that names that begin with an underscore followed by an uppercase letter, or that contain two consecutive underscores, are reserved to the (compiler and standard library) implementation for any use.
