typedef struct dmi_dell_infrared_port {
const char *location;

dmi_dell_enable_state_t speed_limit_state;

} dmi_dell_infrared_port_t;Description
The dmi_dell_infrared_port_t structure holds the decoded Dell infrared port
structure (type 211): where an infrared port is, whether it and its speed limit
are enabled, its protocol, and the legacy ports it is seen as.
The structure is returned by dmi_entity_info for the structures of type
DMI_TYPE(dell_infrared_port), declared in <opendmi/module/dell.h>, and
lives as long as the context it has been decoded in.
The structures are told by their length of 13 bytes, since structures of other lengths are found at the same type, e.g. the one of 17 bytes of Studio 1555, which holds text in its formatted area. Those are not decoded.
Fields
location-
Location of the port.
nullptrwhen the structure carries no string. state-
Whether the port is enabled.
speed_limit_state-
Whether the speed limit is enabled.
speed_limit-
Speed limit, in bits per second. The structure carries it in hundreds of bits per second, which is assumed rather than known: no source gives the unit, and no data confirms it.
physical_port-
Name of the physical port.
nullptrwhen the structure carries no string. virtual_com_port-
Name of the virtual COM port the infrared port is seen as.
nullptrwhen the structure carries no string. virtual_lpt_port-
Name of the virtual LPT port the infrared port is seen as.
nullptrwhen the structure carries no string. protocol-
Infrared protocol of the port.
Examples
dmi_registry_t *registry = dmi_get_registry(context);
dmi_entity_t *entity = dmi_registry_lookup_first(registry,
DMI_TYPE(dell_infrared_port), true);
dmi_dell_infrared_port_t *port = dmi_entity_info(entity,
DMI_TYPE(dell_infrared_port));
if (port != nullptr) {
const char *proto = dmi_dell_infrared_proto_name(port->protocol);
printf("Infrared port: %s, limit %u bit/s\n",
proto != nullptr ? proto : "?", (unsigned)port->speed_limit);
