Method, system, and program for managing access to a device by device specific components and operating system specific components

摘要

Provided are a method, system, and program for managing access to at least one device coupled to a computer system. A set of operating specific functions perform operating system related operations related to managing access to the at least one device. A set of device specific functions performs operations that interact with the device. The operating system specific functions and device specific functions are loaded into memory. Pointers to the operating system specific functions and device specific functions in memory are added to at least one function pointer list accessible to a device specific module and operating system module executing in the computer system. The device specific module and the operating system specific module access the pointers in the function pointer list to call the operating system specific functions and device specific functions.
