dmi_port_connector
Synopsis
#include <opendmi/entity/port-connector.h>
typedef struct dmi_port_connector {
const char *internal_designator;
dmi_connector_type_t internal_connector;
const char *external_designator;
dmi_connector_type_t external_connector;
dmi_port_type_t port_type;
} dmi_port_connector_t;Description
The dmi_port_connector_t structure holds the decoded port connector
information structure (type 8) of SMBIOS: what a port of the system is for
(serial, parallel, keyboard, USB, network…), and the connectors it has inside
and outside the enclosure. A table carries one such structure for each port.
A port without an internal connector, such as one soldered onto the board and
reaching out of the chassis, has no internal designator and the internal
connector type DMI_CONNECTOR_TYPE_NONE; a port without an external connector,
such as the sound input of an optical drive, has the same for the external
side.
The structure is returned by dmi_entity_info for the structures of type
DMI_TYPE(port_connector), and lives as long as the context it has been
decoded in.
Fields
internal_designator-
Reference designator of the connector inside the enclosure, such as "J12";
nullptrif the structure does not carry it. internal_connector-
Type of the connector inside the enclosure, see
dmi_connector_type. external_designator-
Reference designator of the connector on the outside of the enclosure, such as "USB 1";
nullptrif the structure does not carry it. external_connector-
Type of the connector on the outside of the enclosure, see
dmi_connector_type. port_type-
Function of the port, see
dmi_port_type.
Examples
dmi_registry_t *registry = dmi_get_registry(context);
dmi_registry_iter_t iter;
dmi_entity_t *entity;
dmi_registry_iter_initialize(&iter, registry, nullptr);
while ((entity = dmi_registry_iter_next(&iter)) != nullptr) {
if (dmi_entity_type(entity) != DMI_TYPE(port_connector))
continue;
dmi_port_connector_t *port = dmi_entity_info(entity,
DMI_TYPE(port_connector));
if ((port != nullptr) && (port->external_designator != nullptr))
printf("%s: %s\n", port->external_designator,
dmi_port_type_name(port->port_type));
