- Use queue(3) -- not some homegrown implementation of linked lists. - Rename structures to _entry, as they are entries in the linked list -- not the lists themselves. - Don't store entire copies of struct utmpx in utmpx_entry, but only the members we're interested in. Large fields such as hostnames are not needed during the execution of the program. - Give structure members useful names, instead of `name'. - While there, use struct timevals instead of time_t's internally. This is not strictly useful, but while we're at it... - Mark stuff static. - Add missing const keywords. - Remove unneeded prototypes. - Remove workaround for sparc64-specific utmp problems. These don't apply to utmpx. - Don't discard entries when timestamps are not monotone. This shouldn't ever happen with utmpx, but discarding them is a bit too harsh. - Remove debug code. We nowadays have `getent utmpx', which can be used to analyze logfiles in depth. - Use proper uppercasing/periods in comments. - Print output of `ac -p' sorted alphabetically, instead of first occurrence. - Properly check against pts/* instead of tty[PQRSpqrs]* to determine whether a TTY is a pseudo-terminal.
