Hello, All.
I've got a little problem when implicit conversion from zero to pointer can
cause
calling of wrong overloaded function. For example, foo(bool a) and foo(void* a)
both can
be called as foo(0) and compiler used to throw error for this call, but in some
(more
complex) cases compiler can silently choose wrong function that leads to crash.
May be somewhere in sources already exists solution for this problem?
If not, class like this can prevent that:
class strictly_pointer
{
void* val;
public:
strictly_pointer(void* v): val(v) {}
strictly_pointer(int) = delete;
operator void*() { return val; }
};
