SYNOPSIS

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

       char *di_lnode_name(di_lnode_t lnode);

       di_node_t di_lnode_devinfo(di_lnode_t lnode);

       int di_lnode_devt(di_lnode_t lnode, dev_t *devt);

PARAMETERS

       lnode	A handle to an lnode.

       devt	A pointer to a dev_t that can be returned.

DESCRIPTION

       These functions return libdevinfo lnode information.

       The di_lnode_name() function returns a pointer to the name associated with lnode.

       The di_lnode_devinfo() function returns a handle to the device node associated with lnode.

       The di_lnode_devt() function sets the dev_t pointed to by the devt parameter to the dev_t associated with lnode.

RETURN VALUES

       The di_lnode_name() function returns a pointer to the name associated with lnode.

       The di_lnode_devinfo() function returns a handle to the device node associated with lnode.

       The  di_lnode_devt()  function  returns	0  if  the  requested  attribute  exists in lnode and was returned. It returns -1 if the requested
       attribute does not exist and sets errno to indicate the error.
