All of the test cases for the %{Ao}, %{Ad}, and %{Ax} directives (in

Does this mean the width is required? I can't easily discern this by
reading the code.
I don't know off the top of my head but from the output of
the program below (on x86 hardware) I'm guessing the default
width is 1 and the precision is taken to be the number of
initial non-zero elements of the array (each of the given
width). It might be worthwhile to enhance the test to
exercise this.
$ cat t.cpp && ./t
#include <rw_printf.h>
int main ()
{
const int a [] = { 0x12345678, 0 };
rw_printf ("%{Ax}\n", a);
}
