handle, the handle to the required device.
no_of_samples, the number of samples to return.
timebase, a code between 0 and the maximum timebase available
(consult the driver header file). Timebase 0 gives the maximum sample
rate available, timebase 1 selects a sample rate half as fast, timebase 2
is half as fast again and so on. For the maximum sample rate, see the
specifications. Note that the number of channels enabled may affect the
availability of the fastest timebases.
oversample, the oversample factor, a number between 1 and 256.
time_indisposed_ms, a pointer to the time_indisposed_ms. This
is the approximate time, in ms, over which the ADC will collect data. If a
trigger is set, it is the amount of time the ADC takes, in ms, to collect a
block of data after a trigger event, calculated as sample interval x
number of points required. Note: The actual time may differ from
computer to computer, depending on how fast the computer can
respond to IO requests.

time_interval_ms, the time interval, in ms, between data points. This can be
no shorter than 1ms.
max_samples, the maximum number of samples that the driver is to store. This
can be no greater than 60000. It is the caller's responsibility to retrieve data
before the oldest values are overwritten.
windowed, if this is 0, only the values taken since the last call to get values are
returned. If this is 1, the number of values requested by get_values are returned,
even if they have already been read by ps_get_values.
