Generating ctags for libc in mac

Question

I'm trying to use the tags of the libc library on a mac (Mountain Lion) through vim. I've generated tags from *.c files in /usr/include (ctags -R /usr/include/*.h). I've set tags to include the generated tags file (set tags+=tags). But, if I try to go to a tag on a function like fseek() it will say "no tags found". How can I solve this?

edit:

I've tried doing ctags /usr/lib/libc.dylib, and now it results in an error saying the file is not sorted. :(

Answer 1

Use this line to generate a usable tags file:

ctags -R --c++-kinds=+p --fields=+iaS --extra=+q /usr/include

Once it's done, :tag fseek should work, as well as <C-]> on an fseek call.

Be sure to read :h tags and :h ctags carefully.
