Constructor

Parameters

  fd | File descriptor of an existing handle

virtual ~SctpSocket | ( |  | ) |
| virtual

Destructor

## Member Function Documentation

virtual Socket* accept | ( | SocketAddr & | addr | ) |
| inlinevirtual

Accept an incoming connection

Parameters

  addr | The socket address of the incoming connection

Returns
  A new SctpSocket if an incoming connection was detected

virtual bool bindx | ( | ObjList & | addresses | ) |
| pure virtual

Bind this socket to multiple addresses

Parameters

  addresses | The list of addresses (SocketAddr)

Returns
  True if the socket bind succeded

virtual bool connectx | ( | ObjList & | addresses | ) |
| pure virtual

Connect this socket to multiple addresses

Parameters

  addresses | the list of addresses (SocketAddr)

Returns
  True if the socket connect succeded

virtual bool getStreams | ( | int & | inbound,
|  | int & | outbound
| ) |  |
| pure virtual

Get the number of negotiated streams

Parameters

  inbound | Number of inbound streams
  outbound | Number of outbound streams

Returns
  True if operation has succeded

virtual int recvMsg | ( | void * | buf,
|  | int | length,
|  | SocketAddr & | addr,
|  | int & | stream,
|  | int & | flags
| ) |  |
| pure virtual

Receive data from a connected socket

Parameters

  buf | The buffer where the data will be stored
  length | The buffer length
  addr | Gets the remote address from which the data was received
  stream | Gets the stream number on which the data was read
  flags | Flags, gets altered on return

Returns
  The number of bytes read

virtual int sendMsg | ( | const void * | buf,
|  | int | length,
|  | int | stream,
|  | int & | flags
| ) |  |
| pure virtual

Send a buffer of data over a connected socket

Parameters

  buf | The data to send
  length | Data length
  stream | The stream number to send over
  flags | Flags, gets altered on return

Returns
  The number of bytes sent

virtual int sendTo | ( | void * | buffer,
|  | int | length,
|  | int | stream,
|  | SocketAddr & | addr,
|  | int | flags
| ) |  |
| pure virtual

Send a message over a connected or unconnected socket

Parameters

  buffer | Buffer for data transfer
  length | Length of the buffer
  stream | The stream number
  addr | Address to send the message to, if NULL will behave like send()
  flags | Operating system specific bit flags that change the behaviour

Returns
  Number of bytes transferred, socketError() if an error occurred

virtual bool setPayload | ( | u_int32_t | payload | ) |
| pure virtual

Set the SCTP payload protocol identifier (RFC 4960)

Parameters

  payload | Payload identifier code

Returns
  True if set successfully

virtual bool setStreams | ( | int | inbound,
|  | int | outbound
| ) |  |
| pure virtual

Set the number of streams

Parameters

  inbound | The number of inbound streams
  outbound | The number of outbound streams

Returns
  True if the number of streams was set

virtual bool subscribeEvents | ( |  | ) |
| pure virtual

Subscribe to SCTP events This method should be called if we need to find from which stream the data came

Returns
  True if subscription has succeeded
