## Constructor & Destructor Documentation

## ◆ wxSocketServer()

wxSocketServer::wxSocketServer | ( | const wxSockAddress & | address,
|  | wxSocketFlags | flags = wxSOCKET_NONE )

Constructs a new server and tries to bind to the specified address.

Before trying to accept new connections, remember to test whether it succeeded with wxSocketBase:IsOk().

Parameters

  address | Specifies the local address for the server (e.g. port number).
  flags | Socket flags (See wxSocketBase::SetFlags()).

## ◆ ~wxSocketServer()

virtual wxSocketServer::~wxSocketServer | ( |  | ) |
| virtual

Destructor (it doesn't close the accepted connections).

## Member Function Documentation

## ◆ Accept()

wxSocketBase * wxSocketServer::Accept | ( | bool | wait = true | ) |

Accepts an incoming connection request, and creates a new wxSocketBase object which represents the server-side of the connection.

If wait is true and there are no pending connections to be accepted, it will wait for the next incoming connection to arrive.

Warning
  This method will block the GUI.

If wait is false, it will try to accept a pending connection if there is one, but it will always return immediately without blocking the GUI. If you want to use Accept() in this way, you can either check for incoming connections with WaitForAccept() or catch wxSOCKET_CONNECTION events, then call Accept() once you know that there is an incoming connection waiting to be accepted.

Returns
  Returns an opened socket connection, or NULL if an error occurred or if the wait parameter was false and there were no pending connections.

See also
  WaitForAccept(), wxSocketBase::SetNotify(), wxSocketBase::Notify(), AcceptWith()

## ◆ AcceptWith()

bool wxSocketServer::AcceptWith | ( | wxSocketBase & | socket,
|  | bool | wait = true )

Accept an incoming connection using the specified socket object.

Parameters

  socket | Socket to be initialized
  wait | See Accept() for more info.

Returns
  Returns true on success, or false if an error occurred or if the wait parameter was false and there were no pending connections.

See also
  WaitForAccept(), wxSocketBase::SetNotify(), wxSocketBase::Notify(), Accept()

## ◆ WaitForAccept()

bool wxSocketServer::WaitForAccept | ( | long | seconds = -1,
|  | long | millisecond = 0 )

Wait for an incoming connection.

Use it if you want to call Accept() or AcceptWith() with wait set to false, to detect when an incoming connection is waiting to be accepted.

Parameters

  seconds | Number of seconds to wait. If -1, it will wait for the default timeout, as set with wxSocketBase::SetTimeout().
  millisecond | Number of milliseconds to wait.

Returns
  true if an incoming connection arrived, false if the timeout elapsed.
