-<p class="Pp">Return the driver-specific software context of
- <var class="Fa">dev</var>. The softc is automatically allocated and zeroed
- when the device is attached. The softc is also initialized and present when
- a device is probed, but is subject to caveats as described in
- <a class="Xr">DEVICE_PROBE(9)</a>. The size of the allocation is determined
- by the device's <var class="Vt">driver_t</var> information used to define
- the driver. The softc typically encapsulates the state of this instance of
- the device.</p>
-<p class="Pp">Driver writers are discouraged from using their own softc
- management mechanisms. Driver writers should not copy such mechanisms found
- in drivers in the tree that predate this function.</p>
