Specialized Device Drivers
==========================
All device drivers that are accessible to application logic are
either: (1) Character device drivers that can be accessed via the
standard driver operations (``open()``, ``close()``, ``read()``,
``write()``, etc.), or (2) block drivers that can be accessing
only as part of mounting a file system or other special use cases
as described in the preceding paragraph.
In addition to this, there are also specialized "drivers" that can
be used only within the OS logic itself and are not accessible to
application logic. These specialized drivers are discussed in the
following section.
.. note::
While special drivers are *internal*, in some cases there are also
character/block drivers that sit on top of these special drivers
and thus expose them to applications.
