Data of the intrinsic integer data type is not referable, i.e. there may not be multiple references to same (piece of) data (same goes for the remaining intrinsic types, the real and the string ones, yet this example may only be adapted for the intrinsic real data type).
For the benefit of those interfaces requiring struct x1f4_nodetype_type
definitions the intrinsic integer type may be described as:
See struct x1f4_nodetype_type.
struct x1f4_nodetype_type integer_type = { "mode", X1f4_E4_MODE, NULL, NULL, NULL, NULL, NULL, NULL, 0, 4, NULL };
The definition specifies some 4 characters long `mode' name and some
X1f4_E4_MODE
id for the data type and about nothing else.
