Question about native method

Hi all, Please advise if native method can be implemented by this way 
as bellow:

method 1:
  in JVM:
     typedef int (*FUNCTYPE)();  //function's return type is int
     FUNCTYPE *nativefunc = (FUNCTYPE)dlsym(handle, "foo");
     
     //four argument
     (*nativefunc)(1, 2.5);

  in share library:
     int foo(int, double);

method 2:
  in JVM:
     typedef int (*FUNCTYPE)(...);  //function's return type is int, 
argument list is '...'
     FUNCTYPE *nativefunc = (FUNCTYPE)dlsym(handle, "foo");
     
     //four argument
     (*nativefunc)(1, 2.5);

  in share library:
     int foo(int, double);
