turbo C: strtok function in <string.h>

Hi!
Can someone show me exactly how to use the function strtok in string.h library? Please am preparing my exam and the teacher didn't explain it clearly!

There are many ways to use (and misuse ) strtok. So I think there is no way to show you "exactly how to use the function strtok".
So what is it that you do not understand from the documentation?
