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.

use chilkat();

$success = 0;

$socket = chilkat::CkSocket->new();

#  Connect to the server using TLS.
$bTls = 1;
$maxWaitMs = 5000;
$success = $socket->Connect("example.com",5000,$bTls,$maxWaitMs);
if ($success == 0) {
    print $socket->lastErrorText() . "\r\n";
    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 < 0) {
    print $socket->lastErrorText() . "\r\n";
    exit;
}

if ($writable != 1) {
    print "The socket did not become writable before the timeout." . "\r\n";
    exit;
}

print "The socket is writable." . "\r\n";
