Usage

Require this script (and auto-complete) then add to ac-sources.

(require 'ac-c-headers)
(add-hook 'c-mode-hook
          (lambda ()
            (add-to-list 'ac-sources 'ac-source-c-headers)
            (add-to-list 'ac-sources 'ac-source-c-header-symbols t)))

Header filenames and symbols in imported headers are completed.

#include <s[tdio.h>]
#include "p[ath/]t[o/]m[y_header.h"]

Customization

ac-c-headers refers the variable cc-search-directories (defined in built-in elisp “find-file.el”) for a list of directories that may contain header file(s).

Therefore, if you are using MinGW in Windows, following configuration may be useful, for example.

(when (string= (window-system) "w32")
  (add-to-list 'cc-search-directories "C:/MinGW/include/"))
