D has some good C support. You can call any C function from `D`
by declaring it `extern(C) <function-signature>`.
The language subset "BetterC" is required for calling D
functions from C though. Unfortunately, the runtime features of
BetterC are limited and some of C's language features aren't
availabe like C99 variable-length-arrays. "BetterC" is like
programming in C with little more comfort but phobos is
unusable which makes BetterC almost no improvement over C.
BetterC helper librarys like Tanya or Tango do exist.
In that case it can indeed be better for you to convert the
program's entry point into D code. This is unfortunate because
it prevents C code bases from using D.
There is a tool [C++ Conversion
Wizard](https://rainers.github.io/visuald/visuald/CppConversion.html) which could be able to convert C++ and C to D but I don't know how good it is and whether it's usable for free on a GNU/Linux derivative OS. It's only half-automatic.
Actually I know about BetterC and how to call C functions from D
and visa versa. I would also disagree that "BetterC" is almost no
improvement over C as about 90% of the language is there!! C++
classes are also supported
