Basic Streaming Data Usage

When using the streaming data interface, via the

vtex10xxA_enable_streaming_data

function, the

user application provides a callback function. Internally, the instrument driver creates a thread and
then  opens  a  socket  for  streaming  data  between  the  host  PC  and  the  instrument.  The  newly
constructed thread does a “blocking” read on the socket, which causes it to “sleep” (become idle)
until  data  arrives.  When  acquisition  data  arrives,  the  thread  begins  executing,  receives  the
acquisition data from the instrument, executes the user-provided callback function, passing in the
newly arrived data, and then returns to the “sleep” state. The callback function can do whatever is
necessary for the application: write the acquisition values to a file on disk, perform limit checking
on  the  acquisition  values,  update  an  application-specific  data  structure  (e.g.,  FIFO)  post  the
acquisition data to a database or spreadsheet, etc. This behavior is illustrated in Figure 6-4, with the
reception of streaming data causing the user-provided callback function to be executed.

NOTE

Since the callback function executes asynchronously in the same process as the main application
thread, it is important that any data or data structures used by both threads are suitably protected to
guarantee consistency. As with any multi-thread application, care must be taken when using inter-
thread communication primitives (e.g., mutexes) to prevent deadlocks and livelocks. Similarly,
performing GUI operations (e.g., updating an on-screen graph) within the callback function needs
to be implemented carefully.
