The ptree_add_node() function adds the node specified by handle chdh as a child node to the node specified by the handle parh. PICL_CANTPARENT is if the child node already has a parent.

The ptree_delete_node() function deletes the node specified by handle nodeh and all its descendant nodes from the tree.

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PICL_STALEHANDLE is returned if the handle is no longer valid.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.
