CL Stream Read

CL Stream Read

Owning Palette:Communications/Intermediate

Requirements:Quanser Rapid Control Prototyping Toolkit, LabVIEW 2020 or newer, Control Design and Simulation Module

Description

The CL Stream Read VI receives data over a stream. The operation of this VI is affected by the blocking mode of the stream connected to its input. Streams have two modes: blocking (the default) and non-blocking. If a CL Stream Call or CL Stream Answer VI is used to create the stream, then the stream will be non-blocking. If a CL Stream Connect or CL Stream Accept VI is used to create the stream then the blocking mode of the stream is determined by the CL Stream Connect or CL Stream Listen VI.

  		•  CL Stream WriteThe CL Stream Write VI writes data to the stream buffer.
  		•  CL Stream Answer

    The CL Stream Answer VI listens for and accepts a connection from a remote host using non-blocking I/O. Non-blocking I/O is used so that the I/O does not interfere with the sample rate of the VI. However, as a result, communication protocols that do not support non-blocking I/O are not supported by the Intermediate Stream VIs.

  		• CL Stream CallThe CL Stream Call VI establishes a connection to a remote host using non-blocking I/O.
