[boost] Interest in C function pointer utility?

In rewriting a plugin interface I use, which for language portability 
uses C function pointers as the entry points, I came up with a 
"make_c_function" utility. I use it to translate C++ functions, any of 
objects, binds, function, members, et. to _real_ C function pointers. 
For example:

class P
{
   public: int foo(int);
};

P p;

extern "C"
{
   void * get_plugin_call(int n)
   {
     if (1 == n)
     {
       return make_c_function<P,int(int)>(
         boost::bind(&p,p::foo,_1));
     }
     else { return 0; }
   }
}

[example much abbreviated from real life use]
