typedef unsigned long ulong;
typedef unsigned char byte;
// hide this method so that it isn't exposed
void change(ulong size, byte* data)
{
	// do something with data
}

// this is the exposed method
template<class T> void change(const T& data)
{
	change(sizeof(T), (byte*)&data);
}

struct MyStruct
{
// some stuff here
};

MyStruct data;
change((char*)&data, sizeof(MyStruct));
