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.

require 'chilkat'

success = false

socket = Chilkat::CkSocket.new()

#  Connect to the server using TLS.
bTls = true
maxWaitMs = 5000
success = socket.Connect("example.com",5000,bTls,maxWaitMs)
if (success == false)
    print socket.lastErrorText() + "\n";
    exit
end

#  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() + "\n";
    exit
end

if (writable != 1)
    print "The socket did not become writable before the timeout." + "\n";
    exit
end

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