38.4 The Echo Area

The echo area is used for displaying error messages (voir la section Errors), for messages made with the message primitive, and for echoing keystrokes. It is not the same as the minibuffer, despite the fact that the minibuffer appears (when active) in the same place on the screen as the echo area. The GNU Emacs Manual specifies the rules for resolving conflicts between the echo area and the minibuffer for use of that screen space (voir (emacs)Minibuffer section `The Minibuffer' dans The GNU Emacs Manual).

You can write output in the echo area by using the Lisp printing functions with t as the stream (voir la section Output Functions), or explicitly.
