A pointer to the object whose
instance data is required.
dToken (somDToken)
A data token for the required
instance data. The SOM API specifies that the data token for accessing the
instance data introduced by a class is found in the instanceDataToken component
of the auxiliary class data structure for that class. The example below
illustrates this.
rc (somToken)
A somToken (that is, a pointer) that points to the data in obj identified
by the dToken. If obj does not contain the requested data identified
by dToken, somDataResolve generates a runtime error.
