This method is used to retrieve the description of the scalar function, including the qualifier name. When the scalar function that is registered with a qualifier in the IP is called, it can use this API call to get scalar function details. This is useful when the IP registers the same scalar function to evaluate multiple scalar function names or when the scalar function supports a variable number of arguments.
