This type is a structure that allows passing arbitrary object data

between two parties that have no or very little shared knowledge about

their respective internal structures for that object.

It's normally passed in arrays, where the array is terminated with an

element where all fields are zero (for non-pointers) or C<NULL> (for
|
||||
element where all fields are zero (for non-pointers) or NULL (for

These arrays can be used to set parameters for some object, to request

parameters, and to describe parameters.
