void UDPSocket::disconnect

(

)

throw (SocketException)

Unset foreign address and port

Returns:

true if disassociation is successful

Exceptions:

SocketException

thrown if unable to disconnect UDP socket

void UDPSocket::sendTo	(	const void *	buffer,
		int	bufferLen,
		const string &	foreignAddress,
		unsigned short	foreignPort
	)			throw (SocketException)

Send the given buffer as a UDP datagram to the specified address/port

Parameters:

	buffer	buffer to be written
	bufferLen	number of bytes to write
	foreignAddress	address (IP address or name) to send to
	foreignPort	port number to send to

Returns:

true if send is successful

Exceptions:

SocketException

thrown if unable to send datagram

int UDPSocket::recvFrom	(	void *	buffer,
		int	bufferLen,
		string &	sourceAddress,
		unsigned short &	sourcePort
	)			throw (SocketException)

Read read up to bufferLen bytes data from this socket. The given buffer is where the data will be placed

Parameters:

	buffer	buffer to receive data
