+# FSET.H -- FSET/FSTATUS parameters (r = read_only, * = internal to FIO).
+# Some of these parameters provide access to the guts of the i/o system and
+# should not be used by packages outside FIO, to avoid a dependence on the
+# inner workings of FIO.  Parameters affecting the file buffer number, types,
+# or sizes are read-only after the first i/o to the file.
