Autzoo.1421 net.bugs.v7 utcsrgv!utzoo!henry Tue Feb 23 19:21:01 1982 plot -Tver temporary As distributed, the Versatec filter in plot(1) makes its scan-conversion temporary in /usr/tmp/raster rather than using a unique name, and leaves it around afterwards. It creates it rw-rw-rw- so that in theory the next user to run Versatec output simply stomps it. Problem: if the first user has a non-zero umask, this doesn't work. Worse, vplot does not complain, and subsequent users get copies of the first user's output rather than their own. This is easily fixed: 1. Change the initialization of picture to be "/tmp/verXXXXXX" (or maybe "/usr/tmp/verXXXXXX"). 2. Precede the creat of picture with mktemp(picture); . You might also want to change the creat mode to 0600. 3. Put an unlink(picture); before the exit() at the end of main. 4. Put an unlink(picture); before the exit() in onintr. The only capability this loses is the ability to replot an old raster file without scan-converting again. This doesn't seem a real problem. In fact, does anybody know why such a useless capability was included in the first place?
