NAME

       picl_walk_tree_by_class - walk subtree by class

SYNOPSIS

       cc [ flag... ] file... -lpicl [ library... ]
       #include <picl.h>

       int picl_walk_tree_by_class(picl_nodehdl_t rooth,
	    const char *classname, void *c_args,
	    int (*callback)(picl_nodehdl_t nodeh, void *c_args));

DESCRIPTION

       The  picl_walk_tree_by_class()  function  visits all the nodes of the subtree under the node specified by rooth. The PICL class name of the
       visited node is compared with the class name specified by classname. If the class names match, then  the  callback  function  specified	by
       callback  is  called  with  the matching node handle and the argument provided in c_args. If the class name specified in classname is NULL,
       then the callback function is invoked for all the nodes.

       The return value from the callback function is used to determine whether to continue or terminate the  tree  walk.  The	callback  function
       returns PICL_WALK_CONTINUE or PICL_WALK_TERMINATE to continue or terminate the tree walk.

RETURN VALUES

       Upon successful completion, 0 is returned. On failure, a non-negative integer is returned to indicate an error.

       PICL_STALEHANDLE is returned if the handle is no longer valid. This occurs if the PICL tree was refreshed or reinitialized.

       PICL_INVALIDHANDLE is returned if the specified handle never existed.  This error may be returned for a previously valid handle if the dae-
       mon was brought down and restarted. When this occurs a client must revalidate any saved handles.

ERRORS

       PICL_NOTINITIALIZED    Session not initialized

       PICL_NORESPONSE	      Daemon not responding

       PICL_NOTNODE	      Not a node

       PICL_INVALIDHANDLE     Invalid handle specified

       PICL_STALEHANDLE       Stale handle specified

       PICL_FAILURE	      General system failure

NAME

       picl_get_first_prop, picl_get_next_prop - get a property handle of a node

SYNOPSIS

       cc [ flag... ] file... -lpicl [ library... ]
       #include <picl.h>

       int picl_get_first_prop(picl_nodehdl_t nodeh, piclprop_hdl_t *proph);

       int picl_get_next_prop(picl_prophdl_t proph, picl_prophdl_t *nextprop);

DESCRIPTION

       The  picl_get_first_prop()  function  gets  the handle of the first property of the node specified by nodeh and copies it into the location
       given by proph.

       The picl_get_next_prop() function gets the handle of the next property after the one specified by proph from the property list of the node,
       and copies it into the location specified by nextprop.

       If there are no more properties, this function returns PICL_ENDOFLIST.

RETURN VALUES

       Upon successful completion, 0 is returned. On failure, a non-negative integer is returned to indicate an error.

       PICL_ENDOFLIST is returned to indicate that there are no more properties.

       PICL_STALEHANDLE is returned if the handle is no longer valid. This occurs if the PICL tree was refreshed or reinitialized.

       PICL_INVALIDHANDLE is returned if the specified handle never existed.  This error may be returned for a previously valid handle if the dae-
       mon was brought down and restarted. When this occurs a client must revalidate any saved handles.

ERRORS

       PICL_NOTINITIALIZED     Session not initialized

       PICL_NORESPONSE	       Daemon not responding

       PICL_NOTNODE	       Not a node

       PICL_NOTPROP	       Not a property

       PICL_INVALIDHANDLE      Invalid handle

       PICL_STALEHANDLE        Stale handle

       PICL_FAILURE	       General system failure

       PICL_ENDOFLIST	       End of list
