NAME

       al_ustr_prev_get - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              int32_t al_ustr_prev_get(const ALLEGRO_USTR *us, int *pos)

DESCRIPTION

       Find  the  beginning  of  a code point before byte offset *pos, then return it.  Note this
       performs a pre-increment.

       On success returns the code point value.  If pos was out of bounds (e.g. past the  end  of
       the  string),  return  -1.   On an error, such as an invalid byte sequence, return -2.  As
       with al_ustr_prev(3alleg5), invalid byte sequences may be skipped while advancing.
