TUserDefinedFunction.CheckParameters Method
Checks that the parameter array has the expected number of arguments, and that no one is an Error. If any argument is an error it is returned in ResultError, since the default in Excel is to stop processing arguments in a function when one is an error.

True if all parameters are correct, false otherwise.
