Accessor
Access the filesystem using the OS API.
This accessor allows to read raw devices. On Windows, raw files need to be read in aligned page size. This accessor ensures reads are buffered into page size buffers to make it safe for VQL to read the device in arbitrary alignment.
We do not support directory operations on raw devices, so this
accessor can not be used in the glob() plugin.
Additionally this accessor does not attempt to interpret the device part of the path components. It will pass the full path string to the underlying OS APIs. This allows us to read arbitrary devices.
