Nice! I always wondered why clamav creates those temp files. That slows down things quite a bit. A bad design. I really like that someone want to improve it. In the longer term: I think virus database should be stored in such a format that it can be just mmap'ed and directly used, without reading it with read() syscalls. This will eliminate yet another mem-to-mem copying. Something like cdb databases of Dan Bernstein: http://cr.yp.to/cdb.html -- vda _______________________________________________ http://lurker.clamav.net/list/clamav-devel.html
