Adding a caption to a tcolorbox \tcblisting

Question

I'm new to the whole TeX world and have finally managed creating my own tcolorbox code box:

Now I would like to caption my code boxes like regular listings.
It should say something like "Code-Snippet 1: Sample Box" below the tcolorbox, similar to this figure:

How would I do this? Is there a way to \caption the tcblisting? Any help would by greatly appreciated and I've added a minimal working example of my box as well:

\documentclass[a4paper,11pt,twoside]{report}
\usepackage{ngerman}                   
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[fleqn]{amsmath}

\usepackage[scaled=.95]{inconsolata}
\usepackage{tcolorbox}
\tcbuselibrary{listings, breakable, skins}
\definecolor{bg}{rgb}{0.85,0.85,0.85}
\renewcommand*\thelstnumber{\makebox[3em][r]{\ifnum\value{lstnumber}<10 0\fi\the\value{lstnumber}}}

\newtcblisting{ccode}
{colback=bg,
colframe=black!70,
enhanced,
listing only,
overlay={\begin{tcbclipinterior}\fill[black!25] (frame.south west)
        rectangle ([xshift=5.1mm]frame.north west);\end{tcbclipinterior}},
listing options={numbers=left, numberstyle=\tiny,   basicstyle=\small\ttfamily, xleftmargin=0.6em, language = c, aboveskip=\smallskipamount, belowskip=\smallskipamount}
}
\begin{document}

\begin{ccode}
#include <stdio.h>

int main()
{
    stub;
}
\end{ccode}
\end{document}

I don't think it's possible to use a \caption without much redefinitions. Here's a version with blend into=listings, which must be done in \AtBeginDocument or after \begin{document}.

The title= will then be used as the long caption text, the short one is given by list text=... -- See the example, please.

To move the caption to the bottom, the title has to be detached and the title box reconfigured.

\tcbuselibrary{listings, breakable, skins}
\definecolor{bg}{rgb}{0.85,0.85,0.85}
\renewcommand*\thelstnumber{\makebox[3em][r]{\ifnum\value{lstnumber}<10 0\fi\the\value{lstnumber}}}

\AtBeginDocument{%
\newtcblisting[blend into=listings]{ccode}[1][]{%
  colback=bg,
  colframe=black!70,
  enhanced,
  listing only,
  overlay={\begin{tcbclipinterior}\fill[black!25] (frame.south west)
      rectangle ([xshift=5.1mm]frame.north west);\end{tcbclipinterior}},
  listing remove caption=false,
  listing options={numbers=left, numberstyle=\tiny,   
    basicstyle=\small\ttfamily, 
    xleftmargin=0.6em, 
    language = c, 
    aboveskip=\smallskipamount, 
    belowskip=\smallskipamount, 
  },
  coltitle=black,
  attach boxed title to bottom center={yshift=-10pt},
  boxed title style={enhanced jigsaw, colback=white, sharp corners, boxrule=0pt},
  #1
}
}
\begin{document}
\lstlistoflistings
\begin{ccode}[list text={C-Programm!},title={Ein primitives C - Programm!}]
#include <stdio.h>

    stub;
}
\end{ccode}
\end{document}

tcolorbox defines listing remove caption=true, i.e use this as an option and provide a caption argument, i.e. define the \newtcblisting with a mandatory argument`.
