------解决方案--------------------
ctags -R --c-kinds=+p --fields=+S /path
我是用上面这个命令生成系统跟标准库函数的tags，然后放到~/.vim目录下，然后codecomeplete插件使用这些tags

------解决方案--------------------
自从Vim发布7.0之后, 就开始支持标签或者叫标签页  :tabnew file   :tabp  :tabn  
ctags+taglist+omni-completion
在src或者下ctags -R就行了
标准库的  /usr/include下 ctags -R   然后把tags挎贝到源目录下
或者在vimrc中加上set tags+=/usr/include/tags
