Text Formatting ⇒ ANSI C code listings

[krislodz]

Hello,
I have to include C code into report using listings package. The current options used are presented on the example below. The pointer sign * is in the middle which is not so nice and maybe the general look can be improved. Has anybody appended C code before and can advice some neat solutions?

Hi,

regarding the pointer sign, you could define a new command (I called it \Myast in my example code) to control the vertical alignment of the sign and then escape to LaTeX inside the lstlisting environment to use the newly defined command. The following example illustrates this approach:

max(int a, int b)

if(a>b) return a;
else return b;
}
void
reconstruct(char |\Myast|x, char |\Myast|y, 
            int table[strlen(x)+1][strlen(y)+1])
...
\end{lstlisting}
\end{document}

That is not a good option in my case, because the source code is taken from file and there is quite a lot of it. It would have to be a method changing the look of * sign in listing directly.
