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:

    

  • osl_Socket_MsgNormal

  • osl_Socket_MsgOOB

  • osl_Socket_MsgPeek

  • osl_Socket_MsgDontRoute

  • osl_Socket_MsgMaxIOVLen
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 size to the given ReceiverAddr. Since there is only send one packet, the function doesn't care about 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
Return
the number of transfered bytes.
