Syntax

Arguments

An enumeration value.

Returns

Exceptions

If a point is passed as digstate that is not a digital point, returns an error value.

A digital state may appear more than once in the digital state table. In this case, the value that StateNo returns may vary. If digstate is the value of a digital point, StateNo returns a code number appropriate for that point.
