[NTLUG:Discuss] OT: C question

[Burton Strauss]

Bus errors are usually hardware specific alignment problems.

(1) What's the hardware and compiler?
(2) Check the man page and make sure your zero is the right 'type' for the
function, e.g. return ((int)0);

All
I have a C program that if compiled with a "return (0);" as the last line in
main(), runs correctly but give a "Bus error(core dump)" message.
If I compile the same C program with a "exit (0);" as the last line in
main(), the run is also correct, and there is no error message.

What is the difference, please?

K&R says: "Within main, return expr is equivalent to exit(expr).  (page 164,
paragraph 2, "The C Programming Language - Second Edition" by Brian W.
Kernighan, Dennis M. Ritchie, Prentice Hall Software Series, Copyright 1988,
1978, by Bell Telephone Laboratories, Incorporated).

The platform is SGI IRIX 6.4

Thank you in advance for any help you may be able to offer Regards Fred
James
