◆ connect()
| int visionary::UdpSocket::connect | ( | const std::string & | ipaddr, |
| std::uint16_t | port | ||
| ) |
connect to a peer via UDP
actually UDP is connectionless, so this method just stored the target address and uses thestored adresse for successive calls to send, \ recv and read.
- Parameters
-
[in] ipaddr string representation of the device ip address ("xx.xx.xx.xx") [in] port number of the device port to connect to (in host byte order)
- Return values
-
0 connect successful (in this case: the socket could be created) -1 connect failed (in this case: no socket could be created or the ip address format is invalid)

◆ read()
|

Read a number of bytes
Contrary to recv this method reads precisely nBytesToReceive bytes.
- Parameters
-
[in] buffer buffer containing the bytes that shall be sent. [in] nBytesToReceive maximum number of bytes to receive.
- Returns
- number of received bytes or (-1) on error
Implements visionary::ITransport.

◆ recv()
|
overridevirtual |
Receive data on socket to device
Receive at most maxBytesToReceive bytes.
- Parameters
-
[in] buffer buffer containing the bytes that shall be sent. [in] maxBytesToReceive maximum number of bytes to receive.
- Returns
- number of received bytes or (-1) on error

Send data on socket to device
All bytes are sent on the socket. It is regarded as error if this is not possible.
- Parameters
-
[in] buffer buffer containing the bytes that shall be sent.
- Returns
- Number of bytes sent or (-1) on error
