What about something like the following. Not sure if you favour a different
approach rather than checking the extents in the sendfile code, but this
certainly gets me moving forward again.
I can work on some tst-sendfile code too if you want - but don’t want to
duplicate effort if you’re alrea

Note that sendfile() *is* available on OSv, and should work (of course,
unless it has bugs)

OSv aims to be Linux compatible, and does implement sendfile() (though
not without problems, as we see).
sendfile() originated in Solaris, IIRC, and variants exist
sendfile is a pretty Linux-centric API and I'm sure it isn't implemented by OSv.
Given that this is erlang and it must support platforms that don't
have sendfile(2)
I suggest you look into how to build it for POSIX (as opposed to
Linux) environment
Thanks,

The erlang app that I’m hacking is sending out some data to a socket and its
using sendfile to do this. This is causing OSv to abort:
