Result

Returns a new socket ID or error message.

Description

Creates a new TCP Socket.
Socket reference numbers are starting at 29000 and counting up for each new socket.

If you call Socket.Connect, you don't need to use this method first as the connect function creates its own socket.
For MBS Plugin 8.3 or newer this may be IPv6 or IPv4 socket.

Examples

Create TCP Socket listening on a port:

Set Variable [$$sock; Value:MBS("Socket.NewTCPSocket")]
If [MBS("IsError")]
    Show Custom Dialog ["Failed to create Socket"; $$sock]
    Exit Script []
End If
Set Variable [$r; Value:MBS("Socket.SetNewConnectionHandler"; $$sock; Get(FileName); "NewConnection")]
Set Variable [$r; Value:MBS("Socket.SetErrorHandler"; $$sock; Get(FileName); "SocketError")]
Set Variable [$r; Value:MBS("Socket.Listen"; $$sock; TCP Receiver::ListenPort)]
If [MBS("IsError")]
    Show Custom Dialog ["Failed to create Socket"; $$sock]
    Exit Script []
End If
