I want to generate empty implementations of procedures defined in a header file. Ideally they should return NULL for pointers, 0 for integers, etc, and, in an ideal world, also print to stderr which function was called.
The motivation for this is the need to implement a wrapper that adapts a subset of a complex, existing API (the header file) to another library. Only a small number of the procedures in the API need to be delegated, but it’s not clear which ones. So I hope to use an iterative approach, where I run against this auto-generated wrapper, see what is called, implement that with delegation, and repeat.
I’ve see Automatically generate C++ file from header? but the answers appear to be C++ specific.
So, for people that need the question spelled out in simple terms, how can I automate the generation of such an implementation given the header file? I would prefer an existing tool – my current best guess at a simple solution is using pycparser.
update Thanks guys. Both good answers. Also posted my current hack.
UML modeling tools are capable of generating default implementation in the language of choice. Generally there is also a support for importing source code (including C headers). You can try to import your headers and generate source code from them. I personally have experience with Enterprise Architect and it supports both of these operations.
