   NAME
         utmpx, wtmpx - utmpx and wtmpx entry formats

         #include <utmpx.h>

   DESCRIPTION
         utmpx(4) is an extended version of utmp(4).

         These files, which hold user and accounting information for such
         commands as who, write, and login, have the following structure as
