Apple: In which case exit() and return() function works in same manner?

 The exit() function is used to exit your program and return control
to the operating system. The return statement is used to return from a
function and return control to the calling function. If you issue a return
from the main() function, you are essentially returning control to the
calling function, which is the operating system. In this case, the return
statement and exit() function are similar.
