al_ustr_prev_get(3)                                        al_ustr_prev_get(3)

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 *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(3), invalid
       byte sequences may be skipped while advancing.
