   NAME
         ttyslot - find the slot in the utmp file of the current user

   SYNOPSIS

   DESCRIPTION
         ttyslot returns the index of the current user's entry in the
         /var/adm/utmp file.  The returned index is accomplished by scanning
         files in /dev for the name of the terminal associated with the
         standard input, the standard output, or the standard error output (0,
         1, or 2).

   FILES
         /var/adm/utmp

   SEE ALSO
         getut(3C), ttyname(3C).

   DIAGNOSTICS
         A value of -1 is returned if an error was encountered while searching
         for the terminal name or if none of the above file descriptors are
         associated with a terminal device.
