DOPOWERHOOKS(9) Kernel Developer's Manual DOPOWERHOOKS(9)

dopowerhooks
run all power hooks

void
dopowerhooks(int why);

The dopowerhooks routine is deprecated. Use pmf_system_suspend(9) instead.

The dopowerhooks() function invokes all power hooks established using the powerhook_establish(9) function. When power is disappearing the power hooks are called in reverse order, i.e., the power hook established last will be called first. When power is restored they are called normal order.

This function is called from the apm(4) driver when a power change is detected.
