c-forward-syntactic-ws

c-forward-syntactic-ws is a Lisp macro in `cc-defs.el'.

(c-forward-syntactic-ws &optional LIMIT)

Forward skip over syntactic whitespace.
Syntactic whitespace is defined as whitespace characters, comments,
and preprocessor directives. However if point starts inside a comment
or preprocessor directive, the content of it is not treated as
whitespace.

LIMIT sets an upper limit of the forward movement, if specified. If
LIMIT or the end of the buffer is reached inside a comment or
preprocessor directive, the point will be left there.

Note that this function might do hidden buffer changes. See the
comment at the start of cc-engine.el for more info.
