Well there is no need to translate a single line. C++ works happily with your
C code.  But instead of creating the list in C (which you had difficulty
with) you would create it in C++.

Gabor gave you a good pointer.  Grep'ing through existing packages is often a
good idea.  If you can stomach reading other people's code ;-)
