Vl-clocking-direction-head->iskew

Get the iskew field from a vl-clocking-direction-head.

Signature

(vl-clocking-direction-head->iskew x) → iskew

Arguments

x — Guard (vl-clocking-direction-head-p x).

Returns

iskew — Type (vl-maybe-clkskew-p iskew).

This is an ordinary field accessor created by defprod.
