Abstract

The invention discloses a program processing method and apparatus, wherein the method comprises: A first function is obtained from a running program, wherein the first function is a function to be processed in the program. A first function signature is extracted from the first function, wherein the first functional feature code for uniquely identifying a first function. A first entry address is located using a first function signature, wherein the first entry address is an entry address of the first function in the program, and in the case of positioning to the first entry address, the first entry address is modified to a second entry address to perform a second function, wherein the second entry address is the entry address of the second function. The program processing method and apparatus solve the technical problem that the related technology needs to re-scan the function address every time the function in the program is hooked, leading to the low efficiency of the program debugging.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a program processing method and device. Background technique [0002] The Detours tool library developed by Microsoft can be used to implement hooking of functions in running binary programs. Using the Detours tool library, you can hook through the public function name, or you can hook through the function address. However, when the Detours tool library hooks a function in a running binary program, it needs to directly provide the function name of the function or provide the address of the function. However, usually when debugging a program that has been compiled into binary code, the function name information has been lost, and the function name of the function cannot be known, and the address of the function can only be found through other debugging methods. However, the program is constantly updated. After the program is updated, the address of the function is moved due to t...
