This is simply a really small wrapper around /dev/mem. Whether it is a worthwhile enough tool to maintain as a package, I have no opinion. But I would like to point out that it is not portable. It assumes a 4k page size and that sizeof(unsigned long) == 4. We have numerous architectures on which one or both of those are not true. That doesn't even take into consideration that poking around in /dev/mem is almost always the wrong thing. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | http://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: RSA v4 4096b: 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187
