  NAME
-    H5Adelete
+    H5Adelete2
  PURPOSE
     Deletes an attribute from a location
  USAGE
     herr_t H5Adelete (loc_id, name)
-        hid_t loc_id;       IN: Object (dataset or group) to have attribute deleted from
-        const char *name;   IN: Name of attribute to delete
+        hid_t loc_id;           IN: Base location for object
+        const char *obj_name;   IN: Name of object relative to location
+        const char *attr_name;  IN: Name of attribute to delete
+        hid_t lapl_id;          IN: Link access property list
  RETURNS
     Non-negative on success/Negative on failure
  DESCRIPTION
-        This function removes the named attribute from a dataset or group.
-    This function should not be used when attribute IDs are open on 'loc_id'
-    as it may cause the internal indexes of the attributes to change and future
-    writes to the open attributes to produce incorrect results.
+    This function removes the named attribute from an object.
