51 * pci-bus-get-child-devhandle

53 * Retrieve the devhandle for the PCI device represented by 'tag'
54 * in the PCI segment represented by 'pc'. The PCI bus's device_t
55 * is the one that's passed in the call, and the device whose handle
56 * is being requested must be a direct child of that bus, otherwise
57 * behavior is undefined.
58 *
59 * Call returns 0 if successful, or an error code upon failure:
60 *
61 * ENOTSUP The device handle implementation for the
62 * PCI bus does not support this device call.
63 *
64 * ENODEV The PCI device represented by the pcitag_t
65 * was not found in a bus-scoped search of the
66 * platform device tree.
