Method and device for patch loading

The invention discloses a method and a device for patch loading. The method for the patch loading comprises the following steps: loading a patch file to a patch area in a first dynamic loading library; determining the address of the patch file in the first process, according to the relative address of the patch file in the first dynamic loading library and the address of the first dynamic loading library in a first process, ,wherein the first process is the process loading the first dynamic loading library; and running the patch file according to the address of the patch file in the first process. According to the method and the device for the patch loading, a plurality of orders of the dynamic loading library to be modified are not need to be modified to enable the process to jump from a position to be modified, correct content of the patch file can be run, running crack of the process caused by the plurality of orders in the dynamic loading library waiting for being modified is avoided, and reliability of t
