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.
