ptree_create_node, ptree_destroy_node - create or destroy a node

#include <picltree.h>

int ptree_create_node(char *name, char *clname,
 picl_nodehdl_t *nodeh);

int ptree_destroy_node(picl_nodehdl_t nodeh);

The ptree_create_node() function creates a node and sets the "name" property value to the string specified in name and the "class" property value to the string specified in clname. The handle of the new node is copied into the location given by nodeh.

The ptree_destroy_node() function destroys the node specified by nodeh and frees up any allocated space. The node to be destroyed must have been previously deleted by ptree_delete_node (see ptree_add_node(3PICLTREE)). Otherwise, PICL_CANTDESTROY is returned.

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PICL_STALEHANDLE is returned if the handle is no longer valid.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

PICL_INVALIDARG PICL_VALUETOOBIG PICL_NOTSUPPORTED PICL_CANTDESTROY PICL_TREEBUSY PICL_NOTNODE PICL_INVALIDHANDLE PICL_STALEHANDLE PICL_FAILURE
