SYNOPSIS

              #include <allegro5/allegro.h>

                 const ALLEGRO_USTR *reject)

DESCRIPTION

       This function finds the first code point in us, beginning from byte offset start_pos, that does not match
       any  code point in reject.  In other words it finds a code point in the complementary set of reject.  Re‐
       turns the byte position of that code point, if any.  Otherwise returns -1.
