>Description:
Add small section to PRINTJOB.C in /usr/src/usr.sbin/lpr/lpd to extract the
source file name from the (LPD) control file and pass it to the input filter,
along with another "identifying" parameter, at the end of the current/normal
parameter string. The last two parameters below are what get added to the
input filter parameter list:
-w132 -l66 -i0 -n xxxx -h xxxx /var/account/lp.printacct -fn .cshrc
This will allow remote LPD's to do special actions on print files based on
their original source file name, and is really intended for use in an input
filter so it can achieve specialization without having to use other, external,
methods to derive meaningful identifying information about the file waiting
for it on STDIN.
