>Description:
Ctags(1) overlooks some functions and macros decived by extra blanks.
1. function
Blanks which follows function name disturbs ctags.
func () {}
^
2. macro
Blanks which follows '#' disturbs ctags.
# define macro() ;
^
>How-To-Repeat:
test.c
------------------------------------------
# define macro() printf("Hello")
func ()
{
print("Hello");
}
------------------------------------------
% ctags -x test.c
%
It should be like this.
func 2 test.c func ()
macro 1 test.c # define macro() printf("Hello")
>Fix:
[/usr/src/usr.bin/ctags/C.c]
