# al\_ref\_cstr(3alleg5)

Allegro 5 API

## NAME

al\_ref\_cstr - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro.h>
  const ALLEGRO_USTR *al_ref_cstr(ALLEGRO_USTR_INFO *info, const char *s)
  ```

## DESCRIPTION

Create a string that references the storage of a C-style string. The information about the string (e.g. its size) is stored in the structure pointed to by the `info` parameter. The 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 string is valid until the underlying C string disappears.

Example:

-

  ```
  ALLEGRO_USTR_INFO info;
  ALLEGRO_USTR *us = al_ref_cstr(&info, "my string");
  ```
