Method and system of debugging static library function

Abstract

The invention discloses a method and a system of debugging a static library function and relates to the technical field of library function debugging. The method comprises the steps of S1, obtaining a library function to be debugged, and changing a function name A of the library function to be debugged into a function name B; S2, building a new debugging function with a function name A in a source code of a program to be executed; S3, when the library function to be debugged needs to be called by the program to be executed, calling the debugging function by the function name A, calling the library function to be debugged by the function name B so as to realize the debugging of the library function to be debugged. According to the method and the system, the function name of the library function is simply changed, the debugging of the library function is realized, the code of the library function does not need to be modified, the library function does not need to be recompiled, the functions of the library function are not changed, only the function name of the library function is changed, the operation is simple, and the modification is easy.

Description

technical field [0001] The invention relates to the technical field of library function debugging, in particular to a method and system for debugging static library functions. Background technique [0002] Static library functions generally refer to the functions provided by the compiler that can be called in the C language source program. It can be divided into two categories, one is the library function stipulated by the C language standard, and the other is the compiler-specific library function. Due to copyright reasons, the source code of the library function is generally invisible, but its external interface can be seen in the header file. The statement of C language is very simple. If you want to use the statement of C language to directly calculate the sin or cos function, you need to write a rather complicated program. Because there is no statement in the C language statement to directly calculate the sin or cos function. Another example is to display a piece of ...

AI Technical Summary

Problems solved by technology

In fact, when writing C language programs, library functions should be used as much as possible, which can not only improve the operating efficiency of the program, but also improve the quality of programming, but due to improper use by developers, many errors often occur, and many errors In the end, it is reflected in the library function, so there needs to be a way to add debugging code to find the cause of the error

[0004] In the prior art, in order to debug library functions, it is usually necessary to modify the source code of the library, add debugging information, and recompile. Specific source code, debugging information cannot be added, resulting in failure to debug
