NAME

       al_ref_ustr - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

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

DESCRIPTION

       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.
