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 in‐
       formation 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 struc‐
       ture 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  off‐
       sets.
