In LPRng-3.6.22, I still have a problem with mildly over-aggressive
behavior in checkpc. Specifically, I have a character special file in
many queues (a null device) which I use in conjunction with Netatalk
filtering and printing. When I run checkpc -A [time] -r -Pqueuename, it
removes the null device from inside the queue.
A check in checkpc looks to see if a file is zero length and will then
remove it if it is older than the time set in the A flag, but doesn't
confirm that it is a regular file. The following simple patch will fix
that, and has been checked on Solaris 2.6 (and I at least examined the
man page for stat on Linux and confirmed that it has the s_IFREG and
S_IFMT constants defined):
