Function: lwarn

lwarn is an autoloaded and byte-compiled function defined in warnings.el.gz.

Signature

(lwarn TYPE LEVEL MESSAGE &rest ARGS)

Documentation

Display a warning message made from (format-message MESSAGE ARGS...).

Aside from generating the message with format-message, this is equivalent to display-warning.

TYPE is the warning type: either a custom group name (a symbol), or a list of symbols whose first element is a custom group name.
(The rest of the symbols represent subcategories and
can be whatever you like.)

LEVEL should be either :debug, :warning, :error, or :emergency
(but see warning-minimum-level and warning-minimum-log-level).

:emergency -- a problem that will seriously impair Emacs operation soon
if you do not attend to it promptly.
:error -- invalid data or circumstances.
:warning -- suspicious data or circumstances.
:debug -- info for debugging only.
