Function/s equivalent to "bwareaopen" and '''bwconhull' supported for C / C++ code generation

This is with reference to code suggested by Image Analyst given here. I am trying to generate a C / C++ code for that particular code. According to the document "Functions and Objects Supported for C and C++ Code Generation", MATLAB functions bwconhull and bwareaopen aren't readily supported for C / C++ code generation. What are the alternative functions I can use?

There does not seem to be any alternative, other than implementing bwconvhull and bwareaopen by yourself, either in C, or using a subset of MATLAB that is suitable for code generation.
