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-in‐
       crement.

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