Configs

Configs is a class that provides access to all configurations of a Display.

class Configs
{
public:
	Configs(const Display& display); 

	Configs(
		const Display& display,
		const FinishedConfigAttribs& attribs
	); 

	Range<Config> All(void) const; 

	bool Empty(void) const; 

	Config First(void) const; 
};

	Gets the configurations for the specified display.
	Gets configurations for the specified display matching the specified attribute values.
	Returns a range of all supported configurations.
	Returns true if there are no matching configs.
	Returns the first config in this set of configurations if it is not empty.
