DEVICE_DELETE_CHILD(9)                       FreeBSD Kernel Developer's Manual

NAME

     device_delete_child - delete a child from a device

SYNOPSIS

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

     int
     device_delete_child(device_t dev, device_t child);

DESCRIPTION

     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.
