turn-on-cwarn-mode

turn-on-cwarn-mode is an alias for `cwarn-mode' in `cwarn.el'.


(turn-on-cwarn-mode &optional ARG)

This function is obsolete since 24.1;
use `cwarn-mode' instead.

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.

With a prefix argument ARG, enable the mode if ARG is positive,
and disable it otherwise. If called from Lisp, enable the mode
if ARG is omitted or nil.
