Allegro 5 API

## NAME

al\_register\_font\_loader - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro_font.h>
  bool al_register_font_loader(char const *extension,
     ALLEGRO_FONT *(*load_font)(char const *filename, int size, int flags))
  ```

## DESCRIPTION

Informs Allegro of a new font file type, telling it how to load files of this format.

The `extension` should include the leading dot (\`.') character. It will be matched case-insensitively.

The `load_font` argument may be NULL to unregister an entry.

Returns true on success, false on error. Returns false if unregistering an entry that doesn’t exist.
