Shouldn't this work?
-------------------------------------------
#include <iostream>
#include <typeinfo>
int main(void)
{
if (typeid(int*).__is_pointer_p())
std::cout << "int* is a pointer.\n";
else
std::cout << "int* is not a pointer?!\n";
return 0;
}
-------------------------------------------
>g++-3.0 pointer.cc
>a.out
int* is not a pointer?!
If it shouldn't work, then how CAN I check if a
template parameter is a pointer or not? I used
to use some overload trick, but recently 3.0 was
changed to refuse my trick (before it only failed
with -pendantic).
