[Qemu-devel] Qemu baseline requirements/portability?

[H. Peter Anvin]

Hi,

I am writing some code I'm hoping will be able to make it into Qemu, but I
can't seem to find what the baseline portability requirements are.  I'm
specifically wondering about newer POSIX features like openat(), which seems
to be used in the 9p filesystem and nowhere else, and what version of glib one
can rely on?

Thanks,
