The dmi_type_id_t enumeration lists the numbers the SMBIOS specification
gives its structure types: 0 through 127 are defined by the specification, and
128 through 255 are available for OEM- and system-specific information. The
extension modules list the numbers of the vendor types in their headers, e.g.
DMI_TYPE_ID_HPE_PROCESSOR in <opendmi/module/hpe.h>. DMI_TYPE_ID() names
them: DMI_TYPE_ID(SYSTEM) is DMI_TYPE_ID_SYSTEM.
A number tells where a structure is found in the table, which
dmi_entity_type_id gives, rather than what the structure is: vendors give
the same OEM numbers to different structures, and place the structures of
others at numbers of their own. What a structure is decoded into is told by
its structure type, see dmi_type, whose id member is the number its
specification gives it.
Numbers are for what the table itself holds: the number a structure is found
at, the structure types of the table, which dmi_type_spec and
dmi_type_name look up in the context, the types the options of the tool
select, and the structures no specification describes, which
dmi_registry_lookup_first_id finds.
