Check Whether a Socket Is Writable

See more Socket/SSL/TLS Examples

Demonstrates Socket.CheckWriteable, which waits for the connected socket to become writable. It returns 1 if writable, 0 if it did not become writable before the timeout, or -1 on error.

$success = $false

$socket = New-Object Chilkat.Socket

#  Connect to the server using TLS.

$success = $socket.Connect("example.com",5000,$bTls,$maxWaitMs)
if ($success -eq $false) {
    $($socket.LastErrorText)
    exit
}

#  Wait up to 5 seconds for the socket to become writable.  Returns 1 if writable, 0 if it did not
#  become writable before the timeout, or -1 on error.
$writable = $socket.CheckWriteable(5000)
if ($writable -lt 0) {
    $($socket.LastErrorText)
    exit
}

if ($writable -ne 1) {
    $("The socket did not become writable before the timeout.")
    exit
}

$("The socket is writable.")
