SDL Development

Somebody suggested that SDL apps do not prompt for command line arguments
unless they were started with the option key held down. It sounds like a
good idea to me, so…

How do you detect whether or not the app has been started with the
option key?

This works for me:

Boolean OptionKeyIsDown(void)
{
KeyMap theKeyMap;

GetKeys(theKeyMap);

if (((unsigned char *) theKeyMap)[7] & 0x04)
{
	return(true);
}

else
{
	return(false);
}

}

I seem to recall that this may be dependent on a US keyboard layout,
thought I could easily be wrong. I haven’t looked at that stuff for ages.

Nope, the virtual keycode for the option key is always the same.

So, in order to see if your application was started with the option key
held down (as in Quake and UT?) is to use the posted code snippet?
