di_link_t di_link_next_by_lnode(di_node_t lnode, di_link_t link, uint_t endpoint);
The handle to the current the link or DI_LINK_NIL.
Specify which endpoint of the link the node or lnode should correspond to, either DI_LINK_TGT or DI_LINK_SRC.
The device node with which the link is associated.
The lnode with which the link is associated.
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 endpoint 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 endpoint matches the lnode specified by lnode.
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.
The di_link_next_by_node() and di_link_next_by_lnode() functions will fail if:
An argument is invalid.
The end of the link list has been reached.
The di_link_next_by_node() function will fail if:
Device usage information is not available in snapshot.
