    Links a writer and reader and creates a stream between them.

    writer

    The device resource that writes data to the stream.

    datatype_icon

    reader

    The device resource that reads data from 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

    enable stream

    A Boolean control that prepares the stream to transmit data.

    True Prepares the stream to transmit data.
    False Waits to enable the stream until Enable Peer to Peer Stream is called.

    Enabling the Stream Programmatically

    To enable the stream when the writer and reader are ready to transfer data, set enable stream to False and use Enable Peer to Peer Stream to enable the stream.

    Default: True

    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.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

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