The three Read Status attributes/properties are useful for observing the progress of your acquisition.
Current Read Position
is the place in the buffer where the next read begins if the
attribute/property is Current Read Position and the
is 0. In any case, the Current Read Position is always where the last read left it.
Total Samples per Channel Acquired
is the total number of samples per channel acquired by the device and transferred into the buffer.
Available Samples per Channel
is computed by first calculating the Current Read Position based on the settings of the
attributes/properties and then subtracting this number from
Total Samples per Channel Acquired.
