About the cpu_bitmap.h header file problem!!!

I am learning cuda c programming using examples from the text “cuda by example”. In the fourth chapter, there is a demonstration to draw julia set which uses a header file “cpu_bitmap.h”. I could not find this header file in my system and hence I am stuck with the program. Can anyone tell me from where I can download the header file ?
