PUFFS_NODE(3)           NetBSD Library Functions Manual          PUFFS_NODE(3)

NAME
     puffs_node -- puffs node routines

LIBRARY
     puffs Convenience Library (libpuffs, -lpuffs)

SYNOPSIS
     #include <puffs.h>

     struct puffs_node *
     puffs_pn_new(struct puffs_usermount *pu, void *priv);

     void *
     puffs_nodewalk_fn(struct puffs_usermount *pu, struct puffs_node *pn,
         void *arg);

     void *
     puffs_pn_nodewalk(struct puffs_usermount *pu, puffs_nodewalk_fn nwfn,
         void *arg);

     void
     puffs_pn_remove(struct puffs_node *pn);

     void
     puffs_pn_put(struct puffs_node *pn);

DESCRIPTION
     puffs_pn_new(pu, priv)
           Create a new node and attach it to the mountpoint pu.  The argument
           priv can be used for associating file system specific data with the
           new node and will not be accessed by puffs.

     puffs_nodewalk_fn(pu, pn, arg)
           A callback for puffs_nodewalk().  The list of nodes is iterated in
           the argument pn and the argument arg is the argument given to
           puffs_nodewalk().

     puffs_nodewalk(pu, nwfn, arg)
           Walk all nodes associted with the mountpoint pu and call nwfn() for
           them.  The walk is aborted if puffs_nodewalk_fn() returns a value
           which is not NULL.  This value is also returned this function.  In
           case the whole set of nodes is traversed, NULL is returned.  This
           function is useful for example in handling the puffs_fs_sync()
           callback, when cached data for every node should be flushed to sta-
           ble storage.

     puffs_pn_remove(pn)
           Signal that a node has been removed from the file system, but do
           not yet release resources associated with the node.  This will pre-
           vent the nodewalk functions from accessing the node.  If necessary,
           this is usually called from puffs_node_remove() and
           puffs_node_rmdir().

     puffs_pn_put(pn)
           Free all resources associated with node pn.  This is typically
           called from puffs_node_reclaim().
