SYNOPSIS

C]
#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 string. The information about the string (e.g. its size) is stored in the structure pointed to by the C]info] parameter. The string will not have any other storage allocated of its own, so if you allocate the C]info] structure on the stack then no explicit "free" operation is required.

The referenced interval is [start_pos, end_pos).

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(3) to find the byte offsets.
