# al\_free(3alleg5)

Allegro 5 API

## NAME

al\_free - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro.h>
  #define al_free(p) \
     (al_free_with_context((p), __LINE__, __FILE__, __func__))
  ```

## DESCRIPTION

Like free() in the C standard library, but the implementation may be overridden.

Additionally, on Windows, a memory block allocated by one DLL must be freed from the same DLL. In the few places where an Allegro function returns a pointer that must be freed, you must use al\_free(3alleg5) for portability to Windows.

This is a macro.
