Synopsis
#include <opendmi/entity/system.h>
typedef struct dmi_system {
const char *vendor;
const char *product;
const char *version;
const char *serial_number;
dmi_uuid_t uuid;
dmi_system_wakeup_type_t wakeup_type;
const char *sku_number;
const char *family;
} dmi_system_t;Description
The dmi_system_t structure holds the decoded system information structure
(type 1) of SMBIOS: the identity of the system as a whole, i.e. its maker,
product name, serial number and UUID, and the event which powered it up. A
table carries exactly one such structure, which is required since SMBIOS 2.3.
The structure is returned by dmi_entity_info for the structures of type
DMI_TYPE(system), and lives as long as the context it has been decoded in.
Fields
vendor-
Name of the manufacturer of the system;
nullptrif the structure does not carry it. product-
Product name of the system;
nullptrif the structure does not carry it. version-
Version of the product;
nullptrif the structure does not carry it. serial_number-
Serial number of the system;
nullptrif the structure does not carry it. uuid-
Universally unique identifier of the system, converted from the byte order of SMBIOS (the first three fields little-endian) to the one of RFC 4122, see
dmi_uuid_decode. All bytes 0 mean that the system has no UUID; all bytes0xFF, that it has none yet but one can be set. Present since SMBIOS 2.1; all zeros in older data. wakeup_type-
Event which powered the system up, see
dmi_system_wakeup_type. Present since SMBIOS 2.1;DMI_SYSTEM_WAKEUP_TYPE_RESERVEDin older data. sku_number-
Stock keeping unit of the system: the identifier of the configuration it was sold in, also known as product ID or order number, in a format the vendor chooses;
nullptrif the structure does not carry it. Present since SMBIOS 2.4. family-
Family of products the system belongs to: models which share their design and branding but differ in configuration and price;
nullptrif the structure does not carry it. Present since SMBIOS 2.4.
Examples
dmi_registry_t *registry = dmi_get_registry(context);
dmi_entity_t *entity = dmi_registry_lookup_first(registry,
DMI_TYPE(system), false);
dmi_system_t *system = dmi_entity_info(entity, DMI_TYPE(system));
if ((system != nullptr) && (system->product != nullptr))
printf("%s (%s)\n", system->product,
dmi_system_wakeup_type_name(system->wakeup_type));
