Template:Modules/Sockets/Functions

This function creates a socket.

Syntax

userdata sockOpen ( string host, int port )

Required Arguments

• host: This is a host name e.g. "www.google.com"
• port: This is the port on which to connect e.g. 80

Returns

Returns userdata if the correct arguments were given false otherwise.

Example

This example shows you how you can connect to irc.

PHP: (for the page that LUA expects to be at http://www.example.com/page.php)

local socket = sockOpen("irc.gtanet.com",80)

addEventHandler("onSockOpened",getRootElement(),
   function (sock)
      if sock == socket then
         sockWrite(socket,"USER IRCbot botname * :Gamesnert & MCvarial")
         sockWrite(socket,"NICK botname")
      end
   end
)

Important Note: Sockets are asynchronous this means if sockOpen() returns the socket isn't actually created!
