And I don't mean to waste your time either. "All" means all, period. The current release versions are irrelevant because you cannot use them in code, they are not conveying any information about the future -- who knows when, if ever, mempcpy() will be added to FreeBSD? Who knows if mempcpy() will make a future issue of the OpenGroup standard specification some day (Single Unix Specification, IEEE Std 1003.1, whichever), as mandatory feature? > Since neither me nor many other bbox hackers will ever use FreeBSD, > sometime in 2020 we will wonder "hmm, in which year mempcpy() > was added for FreeBSD compat?

"None of the FreeBSD releases as of 2015-02-04 offer mempcpy()." Add a snapshot of <https://www.freebsd.org/security/#sup> and perhaps the SVN revision from the log below, as comments, that is as close as you will get. For development versions, the common FreeBSD idiom is "feature foo() added in SVN r123456", and often - if it is an important feature - the OSVERSION is bumped so that there is a quick way to compare without knowing the SVN version. > Why you can't help me with this by simply looking at your version > of FreeBSD and letting me know it?

You might just trust that the information I have provided is accurate. "All" means just that. Including the development SVN branch as of the date of writing, and still current today, <https://svnweb.freebsd.org/base/head/include/string.h?view=markup>. > But I should not be forced to guess. You could just answer a simple question. You could just take the answer literally. _______________________________________________ busybox mailing list [email protected] http://lists.busybox.net/mailman/listinfo/busybox
