These interfaces are only provided for compatibility purpuses and have been superseeded by endutxent(3), utmpx(5).
getutent() reads the next entry from the
    database; if the database was not yet open, it also opens it.
    setutent() resets the database, so that the next
    getutent() call will get the first entry.
    endutent() closes the database.
getutline() returns the next entry which
    has the same name as specified in the ut_line field,
    or NULL if no match is found.
pututline() adds the argument
    utmp(5) entry line to the
    accounting database, replacing a previous entry for the same user if it
    exists.
utmp structure has the following definition:
struct utmp {
        char ut_line[UT_LINESIZE];    /* tty name */
        char ut_name[UT_USERSIZE];    /* login name */
        char ut_host[UT_HOSTSIZE];    /* host name */
	time_t ut_time;		      /* time entry was created */
};
getutent() returns the next entry, or
  NULL on failure (end of database or problems reading
  from the database). getutline() returns the matching
  structure on success, or NULL if no match was found.
  pututline() returns the structure that was
  successfully written, or NULL.
endutent(), getutent(),
  getutline(), pututline(),
  setutent() functions all conform to
  X/Open Portability Guide Issue 4, Version 2
  (“XPG4.2”).
