i dont know what foo is and google didnt help, does anybody know, thanks 
wikipedia had it? google didnt even come up with that. then again i was using the schools wifi in the library
Wow, I too have wondered that for years. Thanks for sharing. I once examined a piece of code that had a foo function in for three hours before I debugged it and concluded it did in fact do nothing. If I had known what foo was I could have saved myself some time, lol.
