Compiler Warning (level 1) C4667

'function' : no function template defined that matches forced instantiation

You cannot instantiate a function template that has not been declared.

The following sample will cause C4667:

// C4667a.cpp
// compile with: /LD /W1
void max(const int &, const int &); // C4667 expected

To avoid this warning, first declare the function template:

// C4667b.cpp
// compile with: /LD
// Declare the function template
template<typename T>
const T &max(const T &a, const T &b) {
   return (a > b) ? a : b;
// Then forcibly instantiate it with a desired type ... i.e. 'int'
const int &max(const int &, const int &);
