CC Mode 5.28 (C++); imenu regexp fails to find some functions


From: Andy . Ling
Subject: CC Mode 5.28 (C++); imenu regexp fails to find some functions
Date: Wed, 27 Mar 2002 11:03:48 +0000

For function definitions that look like :-

void myFunction
(
  int arg1,
  int arg2
)
{
}

The imenu regexp fails. the following changes to cc-menus.el seems to fix
it

> diff -c cc-menus.el cc-menus.el.orig
