Provides a TCP implementation over IG Stream Base. All of the low-level TCP is entirely native LabVIEW functionality so it runs on all supported LabVIEW programs. The library runs connection management asynchronously to enable more parallel operation. TCP Servers enable multiple simultaneous incoming connections whereas Clients establish single connections to a specific server.

Connection notification is handled with VI Callback mechanisms that provide new connections as they are established or when existing connections disconnect. From these connections the underlying TCP stream class to begin reading/writing data.

For a simpler messaged based interface that can utilize this TCP library check out the IG Simple Msg package.

An example of a multi-client chat application is available in this package.

- Raise error instead of silently ignoring Reads when a TCP ref has gone invalid.
- Eliminate race condition in server registration of new clients
