function foobar in C language

[subdural]

Hi
I'm a newbie. what is foobar (c source code) in embedded C language? can somebody explain how its works?

example:
C = foobar (a, b)

foo or whaterever foobar is just a generic name used in examples .Is not really a meaningful function or something else .Is like calling :
doing_something(a)

you see often foo() .is just a example of your real application and how you will call it !

"foobar" is a deliberate humorous misspelling of the old US Army term "fubar". Look it up on the web if you are curious what it means. Also "snafu".
