Use the hostAddress function to find the IP address of the computer that Revolution is running on.

Parameters:

The host is an IP address or domain name.

The port is the number of the port the socket is connected to.

The connectionID is a string identifying the socket.

Value:

The hostAddress function returns the IP address of the computer. This address is in the form X.X.X.X, where each X is a number with between 1 and 3 digits.

Comments:

The socket must be open. If the specified socket has not been opened, the hostAddress function returns "not an open socket". If you have issued an open socket command to create the socket, you cannot use the hostAddress function until after the socket has been created and the command has completed.

The connectionID is needed only if more than one socket is connected to the same port of the same host. The connectionID is assigned by the accept or open socket command that created the socket.
