getPort()

unsigned short DTrackNet::UDP::getPort

(

)

Get UDP data port where data is received.

Returns

Port number

getRemoteIp()

unsigned int DTrackNet::UDP::getRemoteIp

(

)

Get IP address of sender of latest received data.

Returns

IPv4 address

Definition at line 269 of file DTrackNet.cpp.

isValid()

bool DTrackNet::UDP::isValid

(

)

Returns if UDP socket is open to receive data.

Returns

Socket is valid

receive()

int DTrackNet::UDP::receive	(	void *	buffer,
		int	maxLen,
		int	toutUs
	)

Receive UDP data.

Tries to receive one packet, as long as data is available.

Parameters

[out]	buffer	Buffer for UDP data
[in]	maxLen	Length of buffer
[in]	toutUs	Timeout in us (micro seconds)

Returns

Number of received bytes, <0 if error/timeout occured

send()

int DTrackNet::UDP::send	(	const void *	buffer,
		int	len,
		unsigned int	ip,
		unsigned short	port,
		int	toutUs
	)

Send UDP data.

Parameters

[in]	buffer	Buffer for UDP data
[in]	len	Length of buffer
[in]	ip	IPv4 address to send data to
[in]	port	Port number to send data to
[in]	toutUs	Timeout in us (micro sec)

Returns

0 if ok, <0 if error/timeout occured
