Hi, Some people started asking about the gethostid() call in linux. gethostid()/sethostid() was supported from libc-4.4.2b onwards but nothing written to query/set it. So I wacked this up in a few minutes and added International support too just as an example of how to do it. Please take out -DNLS from the Makefile if you don't want International support. If you do want it then you must also have the `gencat' binary to compile a catalog for your own language. Look in sunsite.unc.edu /pub/Linux/utils/nls/catalogs/cat-pack.tar.gz I had actually sent this to Rik Faith for inclusion in his util-1.x package a while ago, but it never showed up. So I release it myelf to the public. Questions/Help to me. Mitch m.dsouza@mrc-apu.cam.ac.uk
