Converting a C++ class to a C struct (and beyond)

Question

Past few days I have been \"downgrading\" > 1000 filem of C++ code into C. It\'s been going well until now. Suddenly I\'m face to face with a class...

The compiler

Answer 1

Turn foobar into a normal struct

struct foobar {
    goo mutex;
};

Create your own "constructor" and "destructor" as functions that you call on that struct

void InitFoobar(foobar* foo)
{
   oneCreate(&foo->mutex);
}

void FreeFoobar(foobar* foo)
{
   oneDestroy(foo->mutex);
}

struct foobar fooStruct;
InitFoobar(&fooStruct);
// ..
FreeFoobar(&fooStruct);

etc
