| int bind | ( | int | port ) |
Bind a UDP Server Socket to a specific port.
- Parameters:
-
port The port to listen for incoming connections on
- Returns:
- 0 on success, -1 on failure.
| int close | ( | bool | shutdown = true ) |
[inherited] |
Set socket options.
- Parameters:
-
level stack level (see: lwip/sockets.h) optname option ID optval option value socklen_t length of the option value
- Returns:
- 0 on success, -1 on failure Get socket options
- Parameters:
-
level stack level (see: lwip/sockets.h) optname option ID optval buffer pointer where to write the option value socklen_t length of the option value
- Returns:
- 0 on success, -1 on failure Close the socket
- Parameters:
-
shutdown free the left-over data in message queues
| int init | ( | void | ) |
Init the UDP Client Socket without binding it to any specific port.
- Returns:
- 0 on success, -1 on failure.
| int receiveFrom | ( | Endpoint & | remote, |
| char * | buffer, | ||
| int | length | ||
| ) |
Receive a packet from a remote endpoint.
- Parameters:
-
remote The remote endpoint buffer The buffer for storing the incoming packet data. If a packet is too long to fit in the supplied buffer, excess bytes are discarded length The length of the buffer
- Returns:
- the number of received bytes on success (>=0) or -1 on failure
| int sendTo | ( | Endpoint & | remote, |
| char * | packet, | ||
| int | length | ||
| ) |
Send a packet to a remote endpoint.
- Parameters:
-
remote The remote endpoint packet The packet to be sent length The length of the packet to be sent
- Returns:
- the number of written bytes on success (>=0) or -1 on failure
| void set_blocking | ( | bool | blocking, |
| unsigned int | timeout = 1500 |
||
| ) | [inherited] |
Set blocking or non-blocking mode of the socket and a timeout on blocking socket operations.
- Parameters:
-
blocking true for blocking mode, false for non-blocking mode. timeout timeout in ms [Default: (1500)ms].
| int set_broadcasting | ( | bool | broadcast = true ) |
Join the multicast group at the given address.
- Parameters:
-
address The address of the multicast group
- Returns:
- 0 on success, -1 on failure. Set the socket in broadcasting mode
- 0 on success, -1 on failure.
