How can I call a function with an argument list built up at run time?

There is no guaranteed or portable way to do this.

Instead of an actual argument list, you might consider passing an array of generic
(void *) pointers. The called function can then step through the array, much like
main() might step through argv. (Obviously this works only if you have control over
all the called functions.)
