    Links the writer and reader in the stream you specify.

    connector_pane_image
    datatype_icon

    session in

    A reference to the stream.

    datatype_icon

    error in

    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

    datatype_icon

    session out

    A reference to the stream.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Linking a Stream

    Linking a stream exchanges hardware addresses between the reader and the writer. You must use an application on the host to link the stream before you can enable the stream. If a stream is in the Unlinked state when this function runs. the stream becomes linked and transitions to the Disabled state. You can use the applications on the host, writer, or reader to enable the stream when the stream is in a Disabled state.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
