How do i make a Windows Console go FULL screen??

is there a function out there for it??

I've seen it done, how can i do it???

& what 'IS' the Console in the Quake 3 Engine, What is it used for??

if there is a function to set the screen res to anything i want, please post it??

If there isn't, could i make one myself??

This is the shell i'd use:


//Screen res function.
void SetRes(int value1, int value2)
{
//Code
}

int main(int arg, char* args)
{

return 0;
}

Please help.....
