connects to the specified host:port and returns a $handle. Check for issues connecting to a host with checkError(). If &closure is specified, this call will not block. &closure will be called when a connection is established.
"host" - the hostname or IP address to connect to
port - the port number to connect to
timeout - the desired timeout (in milliseconds), 0 specifies an indefinite timeout, default is 60 seconds
&closure - if a closure is specified, this function will not block, instead when the connection is established, &closure will be called.
When called, the closure receives the following arguments:
Argument Description $1 a $handle for the connected socket
option => value - various socket options.
linger => n - the value of SO_LONGER (how long (in milliseconds) the socket waits for a TCP reset before closing)
lport => n - the local port to bind to
laddr => "127.0.0.1" - the local address to bind to
A $handle to a socket. This handle can be read from and written to using Sleep's IO functions.
$handle = connect(@ARGV, 31337); println($handle, "hello echo server"); $text = readln($handle); println("Read: $text"); closef($handle);
$ java -jar sleep.jar echocl.sl 127.0.0.1 Read: PONG! hello echo server
