1. For your own sake, forget about the fact that C-style casts like the
above exist. I haven't found the need for one in over 1M lines of code and
you surely don't have such a case here.
Conversion from a typed pointer to a void pointer is implicitly done by the
compiler, so a cast isn't necessary. If you absolutely want, use a
static_cast, which is also the right cast to convert to a typed pointer
again.
2. Igor already mentioned it, this can't be the code you tried to compile,
please show the real code for an analysis of its problems.
