NAME

6       al_ustr_prev_get - Allegro 5 API
7

SYNOPSIS

9              #include <allegro5/allegro.h>
10
11              int32_t al_ustr_prev_get(const ALLEGRO_USTR *us, int *pos)
12

DESCRIPTION

14       Find the beginning of a code point before byte offset *pos, then return
15       it.  Note this performs a pre-increment.
16
17       On success returns the code point value.  If  pos  was  out  of  bounds
18       (e.g.  past the end of the string), return -1.  On an error, such as an
19       invalid byte sequence, return -2.   As  with  al_ustr_prev(3),  invalid
20       byte sequences may be skipped while advancing.
