dam_describeScalarEx

This function is used to retrieve the description of the scalar function. When the IP registered scalar function is called it can use this API call to get scalar function details. This is useful when an IP registers the same C function to evaluate multiple scalar function names or when scalar function supports variable number of arguments.
