typedef that consist function

[kundasang]

I know that
typedef unsigned short int USHORT; // make USHORT as unsigned int
type

what if
typedef void (*VPF)(int&,int&); // make ??

ops suppose to make USHORT as unsigned short int

ops suppose to make USHORT as unsigned short int

that makes VPF a function pointer type to a function which take two
ints( actually references, but the caller wont know ) and return a
void

Well, then it means that code such as this:

void test(USHORT& a, USHORT& b);
VPF testp = test;

is valid code but

void test(int& a, int& b);
VPF testp = test;

is not valid code. What exactly are you trying to ask?

If you wonder what the typedef does, here:

c++decl> explain void (*VPF)(int&,int&);
declare VPF as pointer to function (reference to int, reference to int) returning void

Substitute USHORT for int if needed.
