Constructors
ICMPSocket
ICMPSocket(
const Socket & socket
);
Creates the ICMPSocket with the SocketImpl from another socket. The SocketImpl must be a ICMPSocketImpl, otherwise an InvalidArgumentException will be thrown.
ICMPSocket
ICMPSocket(
SocketAddress::Family family,
int dataSize = 48,
int ttl = 128,
int timeout = 5000000
);
Creates an unconnected ICMP socket.
The socket will be created for the given address family.
ICMPSocket 
ICMPSocket(
SocketImpl * pImpl
);
Creates the Socket and attaches the given SocketImpl. The socket takes ownership of the SocketImpl.
The SocketImpl must be a ICMPSocketImpl, otherwise an InvalidArgumentException will be thrown.
Destructor
~ICMPSocket 
~ICMPSocket();
Destroys the ICMPSocket.
Member Functions
dataSize
int dataSize() const;
Returns the data size in bytes.
mtu 
static Poco::UInt16 mtu(
const SocketAddress & address,
Poco::UInt16 sz
);
Returns minimum payload path MTU size for the destination, or 0 if MTU can not be determined.
operator =
ICMPSocket & operator = (
const Socket & socket
);
Assignment operator.
Releases the socket's SocketImpl and attaches the SocketImpl from the other socket and increments the reference count of the SocketImpl.
packetSize
int packetSize() const;
Returns the packet size in bytes.
receiveFrom
int receiveFrom(
SocketAddress & address,
int flags = 0
);
Receives data from the socket. Stores the address of the sender in address.
Returns the time elapsed since the originating request was sent.
sendTo
int sendTo(
const SocketAddress & address,
int flags = 0
);
Sends an ICMP request through the socket to the given address.
Returns the number of bytes sent.
timeout
int timeout() const;
Returns the socket timeout value.
ttl
int ttl() const;
Returns the Time-To-Live value.
