I don't quite get what you are doing. Why would you need to modify
libvirt to wrap it in a nodejs-based script? What is that
libvirt/wrappers folder you are mentioning? there is no such thing in
the libvirt repository.
>From what I understood from the nodejs-ffi page, you should mostly write
javascript code similar to this:
------------ %< ------------
var ref = require('ref');
var ffi = require('ffi');
var virConnect = ref.types.void;
var virConnectPtr = ref.refType(virConnect);
var libvirt = ffi.Library('libvirt', {
'virInitialize': [ 'int', [ ] ],
'virConnectOpen': [virConnectPtr, [ string ]],
...
});
------------ %< ------------
I'm pretty sure generating this could be automated by a small program or
script or even a clang plugin, using include/libvirt/libvirt.h.in as
input.

I case you really want to modify libvirt, then you should proceed as
mentioned on this page:
