macOS exited with status huh? (curiosity killed the cat)

[Darkroom]

so i'm doing some beginner code stuff with NSLog() function and i've noticed something particular:

int main()
{
	int x = 8;
	float y = 10.5;
	float z = x * y;
    NSLog (@"iMac calculates that %d * %.1f = %.0f", x, y, z);
	return 10000;
}

log returns:

2008-05-26 05:46:04.041 nothing[1672:10b] iMac calculates that 8 * 10.5 = 84

The Debugger has exited with status 16.The Debugger has exited with status 16.

so why does "return 10,000;" exit with status 16? and "return 112541233;" exit with status 49? etc?

Why are you even returning these values in the main function anyway? It should return 0 for success or if you hit some error handling code return -1 for failure.

right, well as i mentioned i was just curious... but thanks for asking...

10000 decimal is also 0x2710

I think the return code is bitmasked with 0x00FF, 0x00FF being the 'user' part of the return code. Hence the exit code of 16. [0x10]

Eh? I was asking a question in the hopes of trying to help. No need to get defensive about it.

sorry, i've been up all night... i was just curious to be honest, i knew i wasn't suppose to write "return 10000", i just did, and put other numbers in and it gave strange results...
