hide-ifdefs

hide-ifdefs is an interactive compiled Lisp function in `hideif.el'.


(hide-ifdefs &optional NOMSG)

Hide the contents of some #ifdefs.
Assume that defined symbols have been added to `hide-ifdef-env'.
The text hidden is the text that would not be included by the C
preprocessor if it were given the file with those symbols defined.
With prefix command presents it will also hide the #ifdefs themselves.

Turn off hiding by calling `show-ifdefs'.
