Parameters

client

The client object that will perform the operation.

This is typically the OpcLabs.EasyOpc.AlarmsAndEvents.EasyAEClient object.

The value of this parameter cannot be null (Nothing in Visual Basic).

eventsSubscriptionArgumentsArray

Array of arguments, one element per each OPC events specification involved in the operation.

The value of this parameter cannot be null (Nothing in Visual Basic).

The individual elements of the parameter value cannot be null (Nothing in Visual Basic).

callback

A callback method to be invoked for each OPC event.

The value of this parameter can be null (Nothing in Visual Basic).

Return Value

This is an extension method (info: C#, VB.NET). In languages that have support for extensions methods (such as C# and VB.NET), you can use the extension method as if it were a regular method on the object that is its first parameter. In other languages (such as with Python.NET), you will call the extension as a static method, and pass it the object on which it acts as its first parameter.
