int main(int argc, char* argv[])

Anything not this (or equivalent, like int main(void)) is not standard.

It doesn't make a big difference but if you are programming for an OS you should always use int main. void main is mostly used when you are programming a microcontroller which has no OS so a return value would be useless.

So basically return value is a must for programming for an OS right?

we've had this discussion before, but maybe this article will explain it better:

What I got was just that void is just not in standard and according to to ultimakillz article its harmful to use too! BTW thanks guys!
