You can use BOOST_PP_LIST_FOR_EACH #define ARG_LIST (char, (int, (unsigned int, (long, ...)))) #define DO_IT(r, data, elem) void foo( elem ); BOOST_PP_LIST_FOR_EACH( DO_IT, , ARG_LIST ) The LIST_FOR_EACH macro repeatedly calls DO_IT for every member in ARG_LIST. In DO_IT, r is the next available LIST_FOR_EACH repetition. data is the middle argument to LIST_FOR_EACH (in our case, nothing), and elem is the current element under inspection (char or int or unsigned int, etc...)

Hi,
I think the preprocessor library could help me here but I'm having problems understanding it. Maybe someone will be so kind to explain it to me a bit. Here is what I want to produce:
void foo(char); void foo(int); void foo(unsigned int); ....
You got the idea. Something that repeats a list of things i.e. here, types. How can I do that?
Thanks! Eric
