NAMEal_ustr_prev_get − Allegro 5 API

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

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