type_info as argument

[cppuser7]

void func(type_info ti) {
  [...]
}

int main() {
  func(typeid(Ball));
}

error: within this context
1>main.cpp(151): error: initializing argument 1 of 'void func(std::type_info)'

Why I receive this error message? typeid() returns a type_info class, so why I can't pass it to func as an argument?

type_info is not copyable. Pass by const reference instead.

Thanks, it works!!

void func(const type_info & ti) {
  [...]
}
