An access control method and device

Abstract

The embodiment of invention provides an access control method and device. The method includes the concrete implement steps that whether a registry callback function located at the tail of a registry callback function chain table is a target registry callback function or not is monitored; the registry callback function chain table is used for storing information of registry callback functions, and the target registry callback function is the registry callback function corresponding to a target client side; if yes, the target registry callback function is migrated to the head from the tail of the registry callback function chain table, so that in the presence of an access requirement of the client side, the target registry callback function is preferentially called to get access to the target client side. Precedence access to the target client side can be achieved by the access control method and device.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an access control method and device. Background technique [0002] With the increasing development of the Internet, there may be multiple similar application clients installed on the user's computer, and some functions of these application clients can be realized by calling the registry callback function. Specifically, each application client can register its own registry callback function during the startup process of the user's computer, and then call its corresponding registry callback function when realizing the target function. [0003] The registry callback functions of each application client are generally stored in the registry callback function linked list of the system. The order of each registry callback function in the registry callback function linked list is generally related to the time when each application client registers the callback function. For example, re...

Problems solved by technology

However, because the registry callback functions of the target client Kingsoft Internet Security are ranked behind, the client was not called for this operation of modifying the system startup items, which reduced its activity in the user's computer.

It can be seen that for an application client, if it registers the callback function relatively late, it is not conducive to ensuring its activity in the user's computer
