Hi Alex, > There are many users of bzero(3) in the wild, and it is a fine API from a > usability point of view. Since you repeatedly claim lots of use of these functions, I did a quick search on https://codesearch.debian.net/ bzero: 21440 memset: 563054 mempcpy: 4489 memcpy: 692873 I used "memcpy(" and "memcpy (" and added the results. These overestimate usage due to prototypes and comments, and don't include memcpy and memset calls emitted by compilers so in reality the results are even more skewed. There may be other repositories which can be easily searched, but these results are clear enough to conclude these functions are dead. Cheers, Wilco
