Overview

IONetworkMedium instances allow network drivers to advertise their media capabilities. This data is encapsulated in the IONetworkMedia class, which offers various structures that hold the data.

Classes

IONetworkMedium: An object that encapsulates information about a network medium (i.e. 10Base-T, or 100Base-T Full Duplex).

Typedefs

IOMediumType

typedef UInt32 IOMediumType;

Discussion

A 32-bit value divided into fields which describes a single medium type.

#defines

kIOMediumFlags

A property of IONetworkMedium objects.

#define kIOMediumFlags "Flags"

Discussion

The kIOMediumFlags property is an OSNumber object that describes a set of attributes assigned to the medium.

kIOMediumIndex

A property of IONetworkMedium objects.

#define kIOMediumIndex "Index"

Discussion

The kIOMediumIndex property is an OSNumber object that describes an index assigned by the owner of the medium object. Its interpretation is driver specific.

kIOMediumSpeed

A property of IONetworkMedium objects.

#define kIOMediumSpeed "Speed"

Discussion

The kIOMediumSpeed property is an OSNumber object that describes the maximum link speed supported by the medium in bits per second.

kIOMediumType

A property of IONetworkMedium objects.

#define kIOMediumType "Type"

Discussion

The kIOMediumType property is an OSNumber object that describes the type of medium that this object represents.
