SetDatatypePropertyEx

This function sets the value(s) of a certain datatypeTypeProperty in the context of an instance.
The value of card gives the actual card of the values list.
The list values of undefined (void) items is a list of booleans, chars, integers or doubles, this list has a length as given in the values card. The actual used type is given by the definition of the dataTypeProperty.
The return value always should be 0, if not something is wrong in the way this property is called.

This call has the same behavior as SetDatatypeProperty, however needs to be used in case properties are exchanged as a successive series of integers.

Note: the client application needs to make sure the cardinality of
the property is within the boundaries.

Property model

Size: 64 bit / 8 byte (value)
The handle to the model. The model handle is static during its existance. Several models can be opened simultaniously within one session. Different models are always independent, threads are allowed to be running on different models simultaniously.

Property rdfsResource

Size: 64 bit / 8 byte (value)
???.

Property owlDatatypeProperty

Size: 64 bit / 8 byte (value)
This attribute represents a handle to the datatype property (attribute). The handle will be static during the life-time of the model, when the model (or part of it) is saved and opened again, the handle will most probably be different.

Property values

Size: 32 bit / 4 byte (reference)
The input array for datatype properties content. The contents memory is allocated by the host

Property card

Size: 64 bit / 8 byte (value)
The cardinality (i.e. number of elements) of the array as given or returned.
