使用emacs获取功能原型

Question

I got a C program edited with emacs.

The C program is not important it looks like

int main(int ac, char **av)
{
....
}
int func(void){...}
int anotherfunc(int a, char c, void *data){...}

can we have a Elisp function which parse the current buffer with those functions and catch the function prototype ?

I already use etags but I just have

int main(
int func(

But i would like have

int main(int ac, char **av)
int func(void)
int anotherfunc(int a, char c,  void *data)

Thanks a lot

我建议看C-eldoc模式- http://www.emacswiki.org/emacs/CEldocMode
