SYNOPSIS #include <allegro5/allegro.h> bool al_ustr_prev(const ALLEGRO_USTR *us, int *pos)
DESCRIPTIONFind the byte offset of the previous code point in string, before *pos. *pos does not have to be at the beginning of a code point. Returns true on success, and the value pointed to by pos will be updated to the found offset. Otherwise returns false if *pos was already at the end of the string, and *pos is unmodified. This function just looks for an appropriate byte; it doesn't check if found offset is the beginning of a valid code point. If you are working with possibly invalid UTF−8 strings then it could skip over some invalid bytes.
