       al_ref_ustr - Allegro 5 API


              #include <allegro5/allegro.h>

              const ALLEGRO_USTR *al_ref_ustr(ALLEGRO_USTR_INFO *info, const ALLEGRO_USTR *us,
                 int start_pos, int end_pos)


       Create  a  read-only  string  that references the storage of another ALLEGRO_USTR(3alleg5)
       string.  The information about the string (e.g. its  size)  is  stored  in  the  structure
       pointed  to  by  the  info  parameter.   The  new  string  will not have any other storage
       allocated of its own, so if you allocate the info structure on the stack then no  explicit
       “free” operation is required.

       The referenced interval is [start_pos, end_pos).  Both are byte offsets.

       The string is valid until the underlying string is modified or destroyed.

       If  you  need a range of code-points instead of bytes, use al_ustr_offset(3alleg5) to find
       the byte offsets.
