ABSTRACT:
The present invention facilitates access to timers in a computing device. In particular, a timer system facilitates configuring a hardware interrupt timer in a computing device, the timer being guaranteed to expire at a specific time in a non-real-time environment. A calling application passes parameters to a hardware independent application programming interface (API) to the hardware interrupt timer. The hardware independent API validates the parameters and relays them to a hardware dependent API. The hardware dependent API establishes a connection with the timer in accordance with the validated parameters, and executes a service routine associated with the application upon expiration of the timer.
