c-clear-char-property-with-value

c-clear-char-property-with-value is a Lisp macro in `cc-defs.el'.

(c-clear-char-property-with-value FROM TO PROPERTY VALUE)

Remove all text-properties PROPERTY from the region [FROM, TO)
which have the value VALUE, as tested by `equal'. These
properties are assumed to be over individual characters, having
been put there by c-put-char-property. POINT remains unchanged.
