di_path_client_next_path(3devinfo)

Device Information Library Functions
                                            di_path_client_next_path(3DEVINFO)



NAME
       di_path_client_next_path, di_path_phci_next_path - libdevinfo path node
       traversal functions

SYNOPSIS
       cc [ flag... ] file... -ldevinfo [ library... ]
       #include <libdevinfo.h>

       di_path_t di_path_client_next_path(di_node_t node node,
            di_path_t path);


       di_path_t di_path_phci_next_path(di_node_t node node,
            di_path_t path);

PARAMETERS
       node    The handle to a device node in  a  di_init(3DEVINFO)  snapshot.
               For  di_path_client_next_path(),  node  must be a client device
               node. For di_path_phci_next_path(), node must be a pHCI  device
               node.


       path    DI_PATH_NIL, or the handle to a path node in a snapshot.


DESCRIPTION
       Each  path  node  is  an element in a pHCI-client matrix. The matrix is
       implemented by dual linked lists: one list links path nodes related  to
       a  common client head, and the other links path nodes related to a com‐
       mon pHCI head.


       The di_path_client_next_path() function is  called  on  a  multipathing
       'client'  device  node,  where a 'client' is the child of a vHCI device
       node, and is associated with a specific endpoint device identity (inde‐
       pendent   of   physical   paths).   If   the  path  argument  is  NULL,
       di_path_client_next_path() returns the first path node associated  with
       the  client.  To walk all path nodes associated with a client, returned
       di_path_t values are fed back into di_path_client_next_path(), via  the
       path  argument, until a null path node is returned. For each path node,
       di_path_bus_addr(3DEVINFO) returns  the  pHCI  child  path  node  unit-
       address.


       The  di_path_phci_next_path() function is called on a multipathing pHCI
       device node. If the path  argument  is  NULL,  di_path_phci_next_path()
       returns  the first path node associated with the pHCI. To walk all path
       nodes associated with a pHCI, returned di_path_t values  are  fed  back
       into di_path_phci_next_path(), via the path argument, until a null path
       node is returned. For  each  path  node,  di_path_client_node(3DEVINFO)
       provides a pointer to the associated client device node.


       A device node can be a client device node of one multipathing class and
       a pHCI device node of another class.

RETURN VALUES
       Upon successful completion, a handle to the next path node is returned.
       Otherwise,  DI_PATH_NIL  is  returned  and errno is set to indicate the
       error.

ERRORS
       These functions will fail if:

       EINVAL     One or more argument was invalid.


       ENOTSUP    Path node information is not available in the snapshot.


       ENXIO      The end of the path node list was reached.
