BUS_CHILD_DETACHED(9)

💅 BUS_CHILD_DETACHED 💅

okay so this is the BUS_CHILD_DETACHED(9) page from the Kernel Developer's Manual, and it's literally about giving a bus device the polite little “hey bestie, your child got detached” notification. no cap.

🌸 NAME 🌸

BUS_CHILD_DETACHED — notify a bus device that a child was detached. iconic behavior, honestly.

✨ SYNOPSIS ✨

#include <sys/param.h>
#include <sys/bus.h>

void
BUS_CHILD_DETACHED(device_t dev, device_t child);

💖 DESCRIPTION 💖

The BUS_CHILD_DETACHED() method is invoked by the new-bus framework after a device is detached, or if a driver's attach routine fails — see DEVICE_ATTACH(9) for that whole situation, iykyk.

A bus driver can provide an implementation of this method to reclaim any resources allocated on behalf of the child, or to cleanup state that wasn't properly released by a DEVICE_DETACH(9) method. it's giving “responsible cleanup era” ✨💅
