Automatic code generating method and automatic code generating device for loading dynamic link library

Abstract

The invention provides an automatic code generating method and an automatic code generating device for loading a dynamic link library. The device comprises an extracting rule editing module, a function prototype and constant definition extracting module, a code template and parameter transformation rule editing module and an object code generating module, wherein the extracting rule editing module is used for defining an extracting rule for an extracting module; the function prototype and constant definition extracting module is used for extracting a function prototype and constant definition list from a header file according to the defined extracting rule; the code template and parameter transformation rule editing module is used for editing a code template and parameter transformation rule; and the object code generating module is used for selecting a corresponding code template and parameter transformation rule according to an object code language and a filling mode, and is used for transforming function prototype and constant definition into object programming language codes. By the scheme, loading codes are generated automatically, demands on developers are reduced, and the developers do not need to concern dynamic loading and static loading specific implementing methods of the DLL (dynamic link library) under optional programming languages, and do not need to be familiar with corresponding relations of parameter types under different languages.

Description

technical field [0001] The invention belongs to the technical field of automatic code generation, and in particular relates to an automatic code generation method and device for loading a dynamic link library. Background technique [0002] There are two ways to load DLL: static loading and dynamic loading. The static loading method includes three static loading methods: [0003] (1) Manually write the code to load the DLL, and the steps adopted by different languages ​​are different: add a reference to the LIB file in the C language, and redefine the functions and constants that need to be called, the definitions of the functions and constants and the header files corresponding to the DLL The definition in is similar, except that the parameter type is changed to the type in the current programming language; in the C# language, create a class, and declare in the class the definition corresponding to the function in the header file; [0004] (2) Under the LabWindows CVI of N...

Although the second method supports the packaging of DLLs in multiple target languages, it relies on Microsoft Visual Studio and can only generate loading codes for programming languages ​​supported by Microsoft Visual Studio; and the process of automatically generating codes has some limitations. This time, all the functions and constants in the FP file are encapsulated, and it is not supported to select the list of functions and constants that need to be encapsulated.
