If less than this number of frames is to be captured or output, applications can request frame skipping or duplicating on the driver side. This is especially useful when using the -:ref:`read() <func-read>` or :ref:`write() <func-write>`, which are +:c:func:`read()` or :c:func:`write()`, which are not augmented by timestamps or sequence counters, and to avoid unnecessary data copying. Finally these ioctls can be used to determine the number of buffers used internally by a driver in read/write mode.
