TCP Listen (G Dataflow)

The network address of a network interface on the local device where this node listens for data.

Default: 0

The name you want to associate with the port number that this node is listening for connections on.

If you specify a service name, this node registers the service name and the associated port number with the NI Service Locator. A client can then use this service name to query the NI Service Locator for the port number associated with that service name. By using registered service names, clients can establish connections with the server without specifying a port number.

The port number where you want to listen for a connection.

By default, this node dynamically chooses an available TCP port to listen for connections on.

The following table lists valid port numbers as defined by the Internet Assigned Numbers Authority (IANA).

Time, in milliseconds, that the node waits for a connection. If the node cannot establish a connection in the specified time, the node returns an error.

Default: -1 — This node waits indefinitely for a connection.

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error	error in contains an error
If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

A Boolean that determines whether to return the remote address as an IP address or as a hostname.

Default: True

A network connection refnum that uniquely identifies the listener.

A network connection refnum that uniquely identifies the connection. Use this value to refer to this connection in subsequent node calls.

The network address of the client that establishes a connection with this server.

The port on the client that establishes a connection with the server.

This node can return the following error codes.
