  14 Section 9P describes kernel properties used by device drivers. Section 9S
  15 describes the data structures used by drivers to share information between the
  16 driver and the kernel. See \fBIntro\fR(9E) for an overview of device driver
  17 interfaces.

 187 Do not declare arrays of structures as the size of the structures can change
 188 between releases. Rely only on the structure members listed in this chapter and
 189 not on unlisted members or the position of a member in a structure.
