device_delete_child9
Delete a child from a device
Usage
#include <sys/param.h>
#include <sys/bus.h>
int
device_delete_child(device_t dev, device_t child);
Overview
The specified device is removed from dev and deleted. If the device is currently attached, it is first detached via device_detach(9). If device_detach() fails, its error value is returned. Otherwise, all descendant devices of child are deleted and zero is returned.
The BUS_CHILD_DELETED(9) method is invoked for each device that is deleted. This permits the parent device's driver to tear down any state associated with child devices such as ivars.
Return values
Zero is returned on success, otherwise an error is returned.
