I do not see this function on:

root@fbsd15:~ # freebsd-version -ku
15.0-RELEASE-p8
15.0-RELEASE-p8

But I once tried "make world" or something like that
to stress test my used laptop. The remains of the build are
still left and they reveal this:

root@fbsd15:~ # nm /usr/obj/home/kalevi/src/freebsd-src/amd64.amd64/tmp/lib/libc.so.7
/usr/obj/home/kalevi/src/freebsd-src/amd64.amd64/tmp/lib/libc.so.7: no symbols
root@fbsd15:~ # strings /usr/obj/home/kalevi/src/freebsd-src/amd64.amd64/tmp/lib/libc.so.7|grep recall
recallocarray

So some versions of FreeBSD libc have recallocarray(),
but the latest official RELEASE does not.

By the way, is reallocarray() or recallocarray()
available on the latest MacOS? ChatGPT gave only a
vague response concerning this, implying "maybe or
maybe not".
