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

 SYNOPSIS
      #include <unistd.h>

      int ttyslot(void);

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

 RETURN VALUE
      ttyslot() returns -1 if an error was encountered while searching for
      the terminal name or if none of file descriptors 0, 1, or 2 is
      associated with a terminal device.

 FILES
      /etc/utmp
