  NAME
-    H5Pencode

  PURPOSE
-    Routine to convert the property values in a property list into a binary buffer
+    Routine to convert the property values in a property list into a binary buffer.
+    The encoding of property values will be done according to the file format 
+    setting in fapl_id.
  USAGE

  RETURNS
     Returns non-negative on success, negative on failure.
