Description

Description:

Checks whether the tested item is Null.
Which null type the item has to be equal to depends on the type of object tested:

• Objects -> objNull
• Controls -> controlNull
• Displays -> displayNull
• Groups -> grpNull
• Locations -> locationNull (since ARMA 2)
• Tasks -> taskNull (since ARMA 2)
• Sides -> sideUnknown (since ARMA 2)

Note: A test via == does not work, because, for example, objNull is not equal to anything, not even to itself.

Uncategorised
