NAME

       al_ustr_prev - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              bool al_ustr_prev(const ALLEGRO_USTR *us, int *pos)

DESCRIPTION

       Find  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.
