Wait for a Socket to Become Writable

See more Socket/SSL/TLS Examples

Demonstrates Socket.SelectForWriting, which waits for the socket, or sockets in a socket set, to become writable. It returns 1 if writable, 0 on timeout, or -1 on error.

Local $bSuccess = False

$oSocket = ObjCreate("Chilkat.Socket")

;  Connect to the server using TLS.
Local $bTls = True
Local $iMaxWaitMs = 5000
$bSuccess = $oSocket.Connect("example.com",5000,$bTls,$iMaxWaitMs)
If ($bSuccess = False) Then
    ConsoleWrite($oSocket.LastErrorText & @CRLF)
    Exit
EndIf

;  Wait up to 5 seconds for the socket (or sockets in a socket set) to become writable.  Returns 1 if
;  writable, 0 on timeout, or -1 on error.
Local $iReady = $oSocket.SelectForWriting(5000)
If ($iReady < 0) Then
    ConsoleWrite($oSocket.LastErrorText & @CRLF)
    Exit
EndIf

If ($iReady <> 1) Then
    ConsoleWrite("The socket did not become writable before the timeout." & @CRLF)
    Exit
EndIf

ConsoleWrite("The socket is ready for writing." & @CRLF)
