Member Function Documentation

getAddress()

Inet4Address nidas::util::Inet4NetworkInterface::getAddress ( ) const

inline

The IPV4 address of the interface.

References _addr.

getBroadcastAddress()

Inet4Address nidas::util::Inet4NetworkInterface::getBroadcastAddress ( ) const

inline

The IPV4 broadcast address of the interface.

References _baddr.

getFlags()

short nidas::util::Inet4NetworkInterface::getFlags ( ) const

inline

The interface flags.

Use macros like IFF_UP, IFF_BROADCAST, IFF_POINTOPOINT, IFF_MULTICAST, IFF_LOOPBACK from net/if.h to check for capabilities. See man netdevice.

References _flags.

Referenced by nidas::util::listMulticastInterfaces().

getIndex()

int nidas::util::Inet4NetworkInterface::getIndex ( ) const

inline

The index of the interface.

References _index.

getInterface()

Inet4NetworkInterface Inet4NetworkInterface::getInterface ( const Inet4Address & addr )

static

Return an Inet4NetworkInterface corresponding to the given address.

If the address does not match the address of an interface on this host, then the Inet4NetworkInterface returned will have a getIndex() value of -1. This static method will throw an IOException if a temporary TCP Socket cannot be created on this host, or if the system call to fetch its interfaces fails.

Exceptions

nidas::util::IOException

References _index, DLOG, nidas::util::Inet4Address::getHostAddress(), and nidas::util::Socket::getInterfaces().

getMTU()

int nidas::util::Inet4NetworkInterface::getMTU ( ) const

inline

The mtu of the interface.

References _mtu.

getName()

const std::string & nidas::util::Inet4NetworkInterface::getName ( ) const

inline

The name of the interface: like "lo", "eth0", etc.

References _name.

getNetMask()

Inet4Address nidas::util::Inet4NetworkInterface::getNetMask ( ) const

inline

The IPV4 network mask of the interface.

References _netmask.
