Method and device for monitoring whether bottom layer interfaces change or not

The invention relates to a method and device for monitoring whether bottom layer interfaces change or not. The method for monitoring whether the bottom layer interfaces change or not comprises the steps of obtaining all the dynamic link libraries of the first edition and the second edition of the bottom layer interfaces, and obtaining all the interfaces of all the dynamic link libraries and functions of all the interfaces; judging whether the functions of the corresponding interfaces of the first edition and the second edition are identical or not; judging the fact that the bottom layer interfaces of the first edition and the bottom layer interfaces of the second edition are identical if the functions of the corresponding interfaces of the first edition and the second edition are identical, and judging the fact that the bottom layer interfaces of the first edition and the bottom layer interfaces of the second edition are different if the functions of the corresponding interfaces of the first edition and the second edition are different. According to the method and device for monitoring whether the bottom layer interfaces change or not, changes of the bottom layer interfaces can be detected quickly and effectively.
