+ NAME
+    H5Pencode1
+ PURPOSE
+    Routine to convert the property values in a property list into a binary buffer
+ USAGE
+    herr_t H5Pencode1(plist_id, buf, nalloc)
+        hid_t plist_id;         IN: Identifier to property list to encode
+        void *buf:              OUT: buffer to gold the encoded plist
+        size_t *nalloc;         IN/OUT: size of buffer needed to encode plist
+ RETURNS
+    Returns non-negative on success, negative on failure.
+ DESCRIPTION
+    Encodes a property list into a binary buffer. If the buffer is NULL, then
+    the call will set the size needed to encode the plist in nalloc. Otherwise
+    the routine will encode the plist in buf.
