Member Function Documentation

AcceptConnection()

virtual eError Burger::NetworkEndpointInstanceTCP::AcceptConnection ( CallbackProc pCallback, void * pContext, void * pExtra )

virtual

Accept a remote connection request.

---

Attempt to connect to the remote endpoint. This can fail if the connection was interrupted before it could be acknowledged.

Parameters

pCallback	Pointer to a callback function that will be called to determine if a connection should be accepted or rejected.
pContext	Pointer to a context for the callback function.
pExtra	Pointer to the Endpoint that issued this accept request.

Returns

Zero if no error, non-zero on error.

Implements Burger::NetworkEndpointInstance.

Close()

virtual eError Burger::NetworkEndpointInstanceTCP::Close ( uint_t bOrderly )

virtual

Close and dispose of a NetworkEndpointInstance.

---

Close an endpoint and if bOrderly is set to TRUE, issue calls to the network driver to notify any connected remote machine that this endpoint is to be shut down and disposed of. If bOrderly is FALSE, the socket is torn down and no attempt is made to notify the machine on the other side.

Parameters

bOrderly

TRUE if the socket is to close in an orderly fashion, FALSE if not.

Returns

Zero if no error, non-zero on error.

Implements Burger::NetworkEndpointInstance.

IsAlive()

virtual uint_t Burger::NetworkEndpointInstanceTCP::IsAlive ( void )

virtual

Test if a stream connection with a remote machine is still active.

---

If a connection with a remote machine is active, return TRUE. Otherwise if the endpoint is invalid or not connected, it will return FALSE.

Returns

TRUE if there is an active connection to a remote endpoint.

Poll()

virtual eError Burger::NetworkEndpointInstanceTCP::Poll ( void )

virtualnoexcept

Poll for events.

---

On some platforms, endpoints require some CPU time from the application to perform housekeeping actions. Most platforms, this call performs no action because the network layer is all performed in its own thread.

Returns

Zero if no error, non-zero on error.

Implements Burger::NetworkEndpointInstance.

ProcessSocket()

void Burger::NetworkEndpointInstanceTCP::ProcessSocket	(	eSocketIndexes	uIndex,
		void *	pInputSet,
		void *	pOutputSet,
		void *	pExecSet )

Receive()

virtual eError Burger::NetworkEndpointInstanceTCP::Receive ( uintptr_t * pBytesReceived, void * pData, uintptr_t uDataSize )

virtual

Receive data using guaranteed protocol.

---

If this endpoint is connected to a remote endpoint, check if the endpoint has data pending and if so, fill the buffer with as many bytes that can be obtained. Set pBytesReceived with the actual number of bytes read in, this value can be zero.

Parameters

pBytesReceived	Pointer to a value that will obtain the number of bytes received during this call.
pData	Pointer to a data buffer to hold the received data.
uDataSize	Size of the buffer that will hold the received data.

Returns

Zero if no error, non-zero on error.

ReceiveDatagram()

virtual eError Burger::NetworkEndpointInstanceTCP::ReceiveDatagram ( uintptr_t * pBytesReceived, void * pData, uintptr_t uDataSize )

virtual

Receive data using non-guaranteed protocol.

---

If this endpoint is listening for packets, check if there is data pending and if so, fill the buffer with as many bytes that can be obtained. Set pBytesReceived with the actual number of bytes read in, this value can be zero.

Parameters

pBytesReceived	Pointer to a value that will obtain the number of bytes received during this call.
pData	Pointer to a data buffer to hold the received data.
uDataSize	Size of the buffer that will hold the received data.

Returns

Zero if no error, non-zero on error.

RejectConnection()

virtual eError Burger::NetworkEndpointInstanceTCP::RejectConnection ( void * pExtra )

virtual

Reject a remote connection request.

---

Reject a connection to a remote endpoint.

Parameters

pExtra

Pointer to the Endpoint that issued an accept request that should be rejected.

Returns

Zero if no error, non-zero on error.

Implements Burger::NetworkEndpointInstance.

Send()

virtual eError Burger::NetworkEndpointInstanceTCP::Send ( uintptr_t * pBytesSent, const void * pData, uintptr_t uDataSize, eBlockMode uMode = kNonBlocking )

virtual

Send data using guaranteed protocol.

---

If this endpoint is connected to a remote endpoint, send data to that endpoint. This function can block until data is in the queue. If the function is not blocked, check the returned pBytesSent value to determine how much data couldn't be sent due to issues such at data blockage.

Parameters

pBytesSent	Pointer to a value that will obtain the number of bytes sent during this call.
pData	Pointer to a data buffer to transmit.
uDataSize	Number of bytes to transmit.
uMode	Either kBlocking if this function should block until error or all data is send or kNonBlocking if the function should return as soon as possible.

Returns

Zero if no error, non-zero on error.

SendDatagram(uintptr_t *,const void *,uintptr_t,eBlockMode)

Implements Burger::NetworkEndpointInstance.

SendDatagram()

virtual eError Burger::NetworkEndpointInstanceTCP::SendDatagram ( uintptr_t * pBytesSent, const void * pData, uintptr_t uDataSize, eBlockMode uMode = kNonBlocking )

virtual

Send data using datagram protocol.

---

If this endpoint has an address for a destination endpoint, send data to that endpoint. This function can block until data is in the queue. If the function is not blocked, check the returned pBytesSent value to determine how much data couldn't be sent due to issues such at data blockage.

Parameters

pBytesSent	Pointer to a value that will obtain the number of bytes sent during this call.
pData	Pointer to a data buffer to transmit.
uDataSize	Number of bytes to transmit.
uMode	Either kBlocking if this function should block until error or all data is send or kNonBlocking if the function should return as soon as possible.
