Function: cwarn-mode

cwarn-mode is an autoloaded, interactive and byte-compiled function defined in cwarn.el.gz.

Signature

(cwarn-mode &optional ARG)

Documentation

Minor mode that highlights suspicious C and C++ constructions.

Suspicious constructs are highlighted using font-lock-warning-face.

Note, in addition to enabling this minor mode, the major mode must be included in the variable cwarn-configuration. By default C and C++ modes are included.

This is a minor mode. If called interactively, toggle the Cwarn mode mode. If the prefix argument is positive, enable the mode, and if it is zero or negative, disable the mode.

If called from Lisp, toggle the mode if ARG is toggle. Enable the mode if ARG is nil, omitted, or is a positive number. Disable the mode if ARG is a negative number.

To check whether the minor mode is enabled in the current buffer, evaluate cwarn-mode(var)/cwarn-mode(fun).

The mode's hook is called both when the mode is enabled and when it is disabled.
