Methods of Class DatagramSocket

DatagramSocket

DatagramSocket(

oslAddrFamily	Family = osl_Socket_FamilyInet,
oslProtocol	Protocol = osl_Socket_ProtocolIp,
oslSocketType	Type = osl_Socket_TypeDgram );

virtual	abstract	const	volatile	template	static	inline	C-linkage
NO	NO	NO	NO	NO	NO	YES	NO

Summary

Creates a datagram socket.

Parameters

Type	is sock_dgram by default.

recvFrom

sal_Int32 recvFrom(

void *	pBuffer,
sal_uInt32	BufferSize,
SocketAddr *	pSenderAddr = 0,
oslSocketMsgFlag	Flag = osl_Socket_MsgNormal );

virtual	abstract	const	volatile	template	static	inline	C-linkage
NO	NO	NO	NO	NO	NO	YES	NO

Summary

Tries to receives BufferSize data from the socket, if no error occurs.

Parameters

pSenderAddr	You must provide pointer to a SocketAddr. It will be filled with the address of the datagrams sender. If pSenderAddr is 0, it is ignored.
pBuffer	Points to a buffer that will be filled with the received datagram.
BufferSize	The size of pBuffer.
Flag	Modifier for the call. Valid values are: <ul> <li> TMsg_Normal <li> TMsg_OOB <li> TMsg_Peek <li> TMsg_DontRoute <li> TMsg_MaxIOVLen </ul>

Return

the number of received bytes.

sendTo

sal_Int32 sendTo(

const SocketAddr &	ReceiverAddr,
const void *	pBuffer,
sal_uInt32	BufferSize,
oslSocketMsgFlag	Flag = osl_Socket_MsgNormal );

virtual	abstract	const	volatile	template	static	inline	C-linkage
NO	NO	NO	NO	NO	NO	YES	NO

Description

Tries to send one datagram with BytesToSend data to the given ReceiverAddr.
Since we only send one packet, we don't need to concern ourselfes here with
incomplete sends due to packet boundaries.

Parameters

ReceiverAddr	A SocketAddr that contains the destination address for this send.
pBuffer	Points to a buffer that contains the send-data.
BufferSize	The number of bytes to send. pBuffer must have at least this size.
Flag	Modifier for the call. Valid values are: - osl_Socket_MsgNormal - osl_Socket_MsgOOB - osl_Socket_MsgPeek - osl_Socket_MsgDontRoute - osl_Socket_MsgMaxIOVLen </ul>

Return

the number of transfered bytes.
