PropertyHandle :: ProvideArea - Provide instance area
The function provides the instance area for a selected property instance. When no instance is selected for a single reference, the function provides an initialized area. When no instance is selected in the upper property handle or when no instance is selected in a collection handle the function returns NULL.
This function will create instances when the appropriate access mode is set (>Read)
Instances do have the type of the referenced property handle (collection type). The instance contains a pointer to a properly structured instance area.
You can use the !-operator or the GetData () function to check whether the instance refers to data or not.
