>Description:
if ctags(1) is working on a typedef whose declarator contains
parenthesis, it won't recognize the typedef'd symbol and won't
recognize the definition following the typedef statement.
>How-To-Repeat:
Run "ctags -t file.c" with file.c containing:
typedef a (*b) _P((c *));
struct s {
int i;
};
This will give you the following tags file:
a test.h /^typedef a (*b) _P((c *));$/
^ Should be "b", because "b" is typedef'd not "a".
i test.h /^};$/
^ This entry shouldn't be there, instead the "s" should be listed.
>Fix:
Here is a patch that partially fixes the problem: The "struct b" will
be listed properly but the typedef'd symbol is still wrong, i. e.
you'll get from file.c the tags file:
c test.h /^typedef a (*b) _P((c *));$/
^ Still wrong.
s test.h /^struct s {$/
^ now correct.
