Description
The SOCKET_OPEN() function is used to open a socket. The <expC> is the IP address or nodename of the server. The <expN1> is the TCPIP port number. The optional <expN2> is the timeout in seconds. The socket number returned from SOCKET_OPEN() should be stored for use in the other socket functions.
Example
// connect to a remote server e.g. node.js listening on port 9000 skt = socket_open("mydomain.com", 9000) if skt < 0 // error endif
