Zhou Li-hua · Computer Technology and Development · 2006
Device driver is a necessary layer when an application communicates with a hardware device.In many device drivers,device events,such as interrupt,data arrival and device error should be sent to the applications.Therefore,choosing a proper device event notifying method is vital when designing a device driver.Five methods of notifying the application of some device event are introduced in this paper.Also presents the program design flow and the details that should be paid attention to when using each method in the device driver.In the end,the application domain and limitations of the five methods are presented in this paper.
