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.

use strict;
use warnings;
use Chilkat2;

my $socket = Chilkat2::Socket->new;

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

# 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.
my $ready = $socket->SelectForWriting(5000);
if ($ready < 0) {
    print $socket->LastErrorText, "\n";
    exit;
}

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

print "The socket is ready for writing.\n";
