[cs631apue] exit() vs return in c programs

In my previous experience with C, I have always used "return 0;" to return from main() function. Those were of course not any system programming codes. However, in the text book APUE, I noticed that they always use "exit(0)" in main(). Can anyone tell me why is that? Is there any significant difference between these two? Or is it just regular practice?
