C- Are there any other statements that serve the function of returning control to OS?

[AmberJain]

HELLO,

One C programming book says:

In ANSI C, it is customary, although not required, to include a statement in main() which explicitly returns control to Operating System

I can think of only two statements that can serve the function of returning control to Operating System i.e.

return 0;

exit(0);

Now my question is that-"Are there any other statements than I mentioned above that serve the function of returning control to OS?"

THANKS in advance......

There's also the Standard abort() function ...

kind regards,

Jos

The only valid returns from main(), exit(), etc are 0 and 1. All others are indeterminate. What the operating system does with this is also indeterminate.

Throw any sort of exception (out of bounds memory access for instance) that causes your program to crash.

Of course the exact state of you entire computer system will be indeterminate on many platforms after this.
