[PATCH v2 19/26] chardev: replace qemu_set_nonblock()

Posted by marcandre.lureau@redhat.com 3 years, 5 months ago

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Those calls are either for non-socket fd, or are POSIX-specific. Use the
dedicated GLib API. (qemu_set_nonblock() is for socket-like)
