The default setup sends output directly to a pipe, # which requires the Ghostscript process to fork, and thus may cause # small systems to run out of memory/swap space. An alternative strategy, # based on a suggestion by Andy Fyfe (andy@cs.caltech.edu), uses a named # pipe for output, which avoids the fork and can thus save a lot of memory. # # Unfortunately this approach can cause problems when a print job is aborted, # as the abort can cause one of the processes to die, leaving the process # at the other end of the pipe hanging forever. # # Because of this, the named pipe method has not been made the default, # but it may be restored by commenting out the lines referring to # 'gsoutput' and uncommenting the lines referring to 'gspipe'. # PBMPLUSPATH=/usr/local/bin PSFILTERPATH=/usr/local/lib/ghostscript LOCALPATH=/usr/local/bin X11HOME=/usr/X11R6 PATH=/bin:/usr/bin:/usr/ucb:/usr/etc PATH=${PATH}\:${LOCALPATH}\:${PBMPLUSPATH}\:${PSFILTERPATH} LD_LIBRARY_PATH=${X11HOME}/lib export PATH LD_LIBRARY_PATH acctfile host user user= host= acctfile=/dev/null # # Redirect stdout to stderr (for the logfile) and open a new channel # connected to stdout for the raw data.
