1/*
2 * Usage: raddr2line input-file address/offset
3 *
4 * This is a tool and is compiled using the host compiler,
5 * i.e. on Linux gcc and not mingw-gcc (cross-compiler).
6 * Therefore we can't include SDK headers and we have to
7 * duplicate some definitions here.
8 * Also note that the internal functions are "old C-style",
9 * returning an int, where a return of 0 means success and
10 * non-zero is failure.
