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, then 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, then *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.
