Wait for a Socket to Become Readable

See more Socket/SSL/TLS Examples

Demonstrates Socket.SelectForReading, which waits for read-ready activity on the socket, or on any contained socket when the object is a socket set. It returns 1 if ready, 0 on 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 read-ready activity on the socket (or, for a socket set, on any contained
#  socket).  Returns 1 if ready, 0 on timeout, or -1 on error.
ready = socket.SelectForReading(5000)
if (ready < 0)
    print socket.lastErrorText() + "\n";
    exit
end

if (ready != 1)
    print "No data became available before the timeout." + "\n";
    exit
end

print "The socket has data ready to read." + "\n";
