type ps2000aDataReady = Option<unsafe extern "C" fn(handle: i16, status: PICO_STATUS, noOfSamples: u32, overflow: i16, pParameter: *mut c_void)>;
This is a callback function that you write to collect data from the driver. You supply a
pointer to the function when you call ps3000aGetValuesAsync, and the driver calls
your function back when the data is ready.
Device identifier returned by OpenUnit.
Indicates whether an error occurred during collection of the data.
