This structure contains information about the number of notification LEDs for the system.
struct NLED_COUNT_INFO {
UINT cLeds;
};
A device usually has one notification LED, although multiple notification devices-LEDs or otherwise-are allowed. For example, multiple notification devices would be appropriate if you want users to be able to select between notification by a blinking LED or by a vibrating buzzer, as is typical with pagers.
Implement this GWES data structure as part of porting native device drivers. This structure is declared in the Nled.h header file.
