    Closes a TCP network connection.

    datatype_icon

    connection ID in

    A network connection refnum that uniquely identifies the TCP connection.

    datatype_icon

    abort

    A Boolean that determines whether this node reserves the TCP connection for future use.

    TRUE The TCP connection is reserved for future use.
    FALSE The TCP connection is not reserved for future use.

    Default: FALSE

    datatype_icon

    error in

    Error conditions that occur before this node runs. Unlike most nodes, this node runs normally even if an error occurs before this node runs.

    Default: no error

    datatype_icon

    error out

    Error information.

    The node produces this output 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.

    How Do I Avoid Losing Unread Data When I Close a Connection?

    If any unread data remains when the TCP connection closes, you might lose the data. To avoid losing data, use a higher level protocol to determine when to close the connection.
