However, the communication interface files for establishing the communication connection all need to be loaded and used by one diagnostic function module after the diagnostic function module is loaded and used, and the process of establishing the communication connection for information transmission by each diagnostic function module is cumbersome. For example, data transmission usually needs to be realized by loading a communication interface file, performing module initialization according to interface functions in the communication interface file, connecting protocol modules, and creating a communication link. Therefore, the processing efficiency of realizing networking communication by each diagnosis function module is low at present.
In order to solve the above problem, embodiments of the present application provide a communication networking method, which can improve the efficiency of each diagnostic function module in implementing networking communication.

Illustratively, the target dynamic link library may be used to perform a function associated with the first program, such as a particular diagnostic function or data processing function, etc. The specific content of the target dynamic link library is not limited herein.
Since the target dynamic link library is associated with the first program, based on the communication interface file loaded by the first program in step S101, other interface functions of the communication interface file may be called to create the second communication link of the target dynamic link library, and it is not necessary to wait for the first program to release the communication interface file and disconnect the first communication link, and then reload the communication interface file by the target dynamic link library to implement communication connection. Therefore, in the embodiment of the application, the target dynamic link library can efficiently call other interface functions of the communication interface file based on the communication interface file loaded by the first program, and create the second communication link of the target dynamic link library, so that the communication connection process is greatly simplified, and the processing efficiency is improved.

In this embodiment, the second program and the first program may have different functions. For example, the first program may be a diagnostic program, and the second program may be a display program, etc. The first program and the second program may belong to different processes, and at this time, if a third communication link of the second program needs to be established, the communication interface file needs to be loaded through the process corresponding to the second program after the first program releases the communication interface file and disconnects the first communication link, so as to connect the second program with a second protocol module according to a second interface function in the communication interface file, and then, based on the second protocol module which is successfully connected, the third communication link of the second program is established.
In some embodiments, before controlling the first program to release the communication interface file, the method further includes:
