Wondering how it's done...

**FlyingIsFun1217** · 12-25-2007

Hey!

I love how certain functions allow developers to pass parameters that are constant. For example, some function to set window properties might only accept the following for arguments:

SCREEN_FULL
SCREEN_WINDOWED
SCREEN_NONE

so you would pass along something as such:

Code:

window.setup(SCREEN_FULL);

Now, obviously these aren't set types (such as intergers, strings, whatever), so they must be defined as a structure somewhere. I just can't figure out how such setup is done.

Can someone point me to an API that does such, possibly something small for me to understand, so that I can figure out how this sort of thing is done?

Thanks so much!

Are you looking for enum?

Code:

enum eMyEnum
{
	TYPE_ONE,
	TYPE_TWO,
	TYPE_THREE
};

void foo(eMyEnum Arg)
{
}

int main()
{
	foo(TYPE_ONE);
	return 0;
}

Yes! That seems to be exactly what I'm looking for!

Thanks, and Merry Christmas
