* Return the number of the slot in the utmp file
* corresponding to the current user: try for file 0, 1, 2.
* To mimic the behavior of getttyent, we loop through utmp
* and try to find an entry with a matching line number.
* If we don't find one we return the index of the end of
* the file, so that the record can be added to the end of
* the file.
