Function Documentation

SbgErrorCode sbgInterfaceUdpAllowBroadcast	(	SbgInterface *	pHandle,
		bool	allowBroadcast
	)

Define if a socket can send broadcasted packets.

Parameters

[in]	pInterface	Pointer on a valid UDP interface created using sbgInterfaceUdpCreate.
[in]	allowBroadcast	Set to true to allow this socket to send broadcasted UDP packets.

Returns

SBG_NO_ERROR if the allow broadcast status has been changed.

Definition at line 376 of file sbgInterfaceUdp.c.

SbgErrorCode sbgInterfaceUdpCreate	(	SbgInterface *	pHandle,
		sbgIpAddress	remoteAddr,
		uint32	remotePort,
		uint32	localPort
	)

Initialize an unconnected UDP interface for read and write operations. An UDP interface can send some data to an output ip address and port and read all received data on a input port.

Parameters

[in]	pHandle	Pointer on an allocated interface instance to initialize.
[in]	remoteAddr	IP address to send data to.
[in]	remotePort	Ethernet port to send data to.
[in]	localPort	Ehternet port on which the interface is listening.

Returns

SBG_NO_ERROR if the interface has been created.

Definition at line 158 of file sbgInterfaceUdp.c.

SbgErrorCode sbgInterfaceUdpDestroy

(

SbgInterface *

pHandle

)

Destroy an interface initialized using sbgInterfaceUdpCreate.

Parameters

[in]

pInterface

Pointer on a valid UDP interface created using sbgInterfaceUdpCreate.

Returns

SBG_NO_ERROR if the interface has been closed and released.

Definition at line 318 of file sbgInterfaceUdp.c.

SbgErrorCode sbgInterfaceUdpInitSockets

(

void

)

Initialize the socket API.

Returns

SBG_NO_ERROR if the socket API has been correctly initialized.

Definition at line 36 of file sbgInterfaceUdp.c.

SbgErrorCode sbgInterfaceUdpRead	(	SbgInterface *	pHandle,
		void *	pBuffer,
		size_t *	pReadBytes,
		size_t	bytesToRead
	)

Try to read some data from an interface.

Parameters

[in]	pHandle	Valid handle on an initialized interface.
[in]	pBuffer	Pointer on an allocated buffer that can hold at least bytesToRead bytes of data.
[out]	pReadBytes	Pointer on an uint32 used to return the number of read bytes.
[in]	bytesToRead	Number of bytes we would like to read.

Returns

SBG_NO_ERROR if no error occurs, please check the number of received bytes.

Definition at line 541 of file sbgInterfaceUdp.c.

SbgErrorCode sbgInterfaceUdpSetSocketBlocking	(	SOCKET	socketHandle,
		bool	blocking
	)

Define if a socket should block or not on receive and send calls.

Parameters

[in]	socketHandle	The socket handle to change.
[in]	blocking	Set to true for a blocking socket or false for a non blocking socket.

Returns

SBG_NO_ERROR if the blocking status has been changed.

Definition at line 92 of file sbgInterfaceUdp.c.

SbgErrorCode sbgInterfaceUdpWrite	(	SbgInterface *	pHandle,
		const void *	pBuffer,
		size_t	bytesToWrite
	)

Try to write some data to an interface.

Parameters

[in]	pHandle	Valid handle on an initialized interface.
[in]	pBuffer	Pointer on an allocated buffer that contains the data to write
[in]	bytesToWrite	Number of bytes we would like to write.

Returns

SBG_NO_ERROR if all bytes have been written successfully.

Definition at line 442 of file sbgInterfaceUdp.c.

SbgErrorCode sbgInterfaceUpdateCloseSockets

(

void

)

Uninitialize the socket API.

Returns

SBG_NO_ERROR if the socket API has been uninitialized.
