# al\_ustr\_compare(3alleg5)

Allegro 5 API

## NAME

al\_ustr\_compare - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro.h>
  int al_ustr_compare(const ALLEGRO_USTR *us1, const ALLEGRO_USTR *us2)
  ```

## DESCRIPTION

This function compares `us1` and `us2` by code point values. Returns zero if the strings are equal, a positive number if `us1` comes after `us2`, else a negative number.

This does *not* take into account locale-specific sorting rules. For that you will need to use another library.
