SAS/C C++ Development System User's Guide, Release 6.50

Template Parameters

The SAS/C C++ Development System supports nontype template parameters as described in the ANSI draft C++ standard. Nontype template parameters types must be

integer types
enumeration types
pointers to functions or objects
references to functions or objects
data member pointers.

Nontype template parameters can use previously declared template parameters in their declaration type. However, template parameters cannot be used in subexpressions within the type. For example:

template <class T, T* someObject> class C { . . . }; int p; C <int, &p> c; template <int I, int a[I]* pArray> class C2; // ok template <int I, int a[I*100]* pBigArray> // error because // of subexpression I*100 class C2;
