di_link_next_by_node(DeviceFInformation Library di_link_next_by_node(3DEVINFO)NAME
di_link_next_by_node, di_link_next_by_lnode - libdevinfo link traversal
functions
SYNOPSIS
cc [ flag... ] file... -ldevinfo [ library... ]
#include <libdevinfo.h>
di_link_t di_link_next_by_node(di_lnode_t node, di_link_t link, uint_t
endpoint);
di_link_t di_link_next_by_lnode(di_node_t lnode, di_link_t link, uint_t
endpoint);
PARAMETERS
link The handle to the current the link or DI_LINK_NIL.
endpoint Specify which endpoint of the link the node or lnode
should correspond to, either DI_LINK_TGT or
DI_LINK_SRC.
node The device node with which the link is associated.
lnode The lnode with which the link is associated.
DESCRIPTION
The di_link_next_by_node() function returns a handle to the next link
that has the same endpoint node as link. If link is DI_LINK_NIL, a
handle is returned to the first link whose endpoint specified by end‐
point matches the node specified by node.
The di_link_next_by_lnode() function returns a handle to the next link
that has the same endpoint lnode as link. If link is DI_LINK_NIL, a
handle is returned to the first link whose endpoint specified by end‐
point matches the lnode specified by lnode.
RETURN VALUES
Upon successful completion, a handle to the next link is returned.
Otherwise, DI_LINK_NIL is returned and errno is set to indicate the
error.
ERRORS
The di_link_next_by_node() and di_link_next_by_lnode() functions will
fail if:
EINVAL An argument is invalid.
ENXIO The end of the link list has been reached.
The di_link_next_by_node() function will fail if:
ENOTSUP Device usage information is not available in snapshot.
