# al\_append\_native\_text\_log(3alleg5)

Allegro 5 API

## NAME

al\_append\_native\_text\_log - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro_native_dialog.h>
  void al_append_native_text_log(ALLEGRO_TEXTLOG *textlog,
     char const *format, ...)
  ```

## DESCRIPTION

Appends a line of text to the message log window and scrolls to the bottom (if the line would not be visible otherwise). This works like printf. A line is continued until you add a newline character.

If the window is NULL then this function will fall back to calling printf. This makes it convenient to support logging to a window or a terminal.
