Thanks Norbert,

What do you mean "That way you have one and only functiob", especially
"functiob" in your sample?

As far as I can see, you still use pointer of function type, other than
function type. So, I doubt whether there are any practical usage for function
type alone. I re-write the code you showed before using function pointer
other than using function type, any drawbacks in my code compared with yours?

[Code]
// define function type
typedef void (*testfunc)(int arg1, int arg2);

void test1(int arg1, int arg2)
{
}

void demo()
{
// pointer to a testfunc

testfunc p = test1;

// call function
p(10, 20);
}
[/Code]
