Pass an array to a wrapped function as pointer+size or range

Given a header like:

#include <iostream>
#include <algorithm>
#include <iterator>

inline void foo(const signed char *arr, size_t sz) {
  std::copy_n(arr, sz, std::ostream_iterator<int>(std::cout, "\n"));
}

inline void bar(const signed char *begin, const signed char *end) {
  std::copy(begin, end, std::ostream_iterator<int>(std::cout, "\n"));
}

(I used C++11 here for convenience, this could be either C or C++ if you changed the implementations though)

How can I wrap these functions to take just an array on the Java side and use the (known) size of the array to provide the second parameter for these functions?
