 .Ss Netgraph Message Structure
 Control messages have the following structure:
 .Bd -literal
 #define NG_CMDSTRSIZ    32      /* Max command string (including null) */
 
 struct ng_mesg {
   struct ng_msghdr {
-    u_char      version;        /* Must equal NG_VERSION */

 .Pp
 Control messages have the fixed header shown above, followed by a
 variable length data section which depends on the type cookie
 and the command.
 Each field is explained below:
 .Bl -tag -width indent
 .It Va version
 Indicates the version of the
 .Nm
 message protocol itself.
 The current version is
-.Dv NG_VERSION .
+.Dv NGM_VERSION .
 .It Va arglen
 This is the length of any extra arguments, which begin at
 .Va data .
 .It Va flags
 Indicates whether this is a command or a response control message.
 .It Va token
 The
