Signature

(url-warn TYPE MESSAGE &optional LEVEL BUFFER-NAME)

Documentation

Display a warning message, MESSAGE.

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, for warning purposes
only, and you can use whatever symbols you like.)

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

:emergency -- a problem that will seriously impair Emacs operation soon
if you do not attend to it promptly.
:error -- data or circumstances that are inherently wrong.
:warning -- data or circumstances that are not inherently wrong,
but raise suspicion of a possible problem.
:debug -- info for debugging only.

BUFFER-NAME, if specified, is the name of the buffer for logging the warning. By default, it is *Warnings*. If this function has to create the buffer, it disables undo in the buffer.

See the warnings custom group for user customization features.

See also warning-series, warning-prefix-function, warning-fill-prefix, and warning-fill-column for additional programming features.

This will also display buttons allowing the user to permanently disable automatic display of the warning or disable the warning entirely by setting warning-suppress-types or warning-suppress-log-types on their behalf.
