 The

 function
 returns an array of
-.Fn statfs

 structures describing each currently mounted file system (see
 .Xr statfs 2 ) .
+As
+.Xr statfs 2
+indicates, the structure is defined differently depending on
+whether the macro _DARWIN_FEATURE_64_BIT_INODE is defined (see
+.Xr stat 2

+.Sh TRANSITIONAL DESCRIPTION (NOW DEPRECATED)
+The
+.Fn getmntinfo64
+routine is equivalent to its corresponding non-64-suffixed routine,
+when 64-bit inodes are in effect.
+It was added before there was support for the symbol variants, and so is
+now deprecated.
+Instead of using it, set the
+.Dv _DARWIN_USE_64_BIT_INODE
