Function typedefs have any use?

["Kevin P. Fleming" <kpfleming@xxxxxxxxxxxxxxx>]

In a header file, I want to declare a struct containing method pointers 
(this is C, not C++). I want to create typedefs for those method 
pointers, so that when the methods are defined later, their signatures 
will match (without having to be hand-written to match).

However, in spite of the fact that I can do:

typedef int method_func(int);

I can't see any way to _use_ this typedef, except to declare the method 
pointer itself. Actual definition of the method has to re-iterate the 
prototype of the function and ensure that it matches.

Is this sort of thing just not possible in standard C?
