I see I was my assumptions were wrong at last function ... it probably
doesn't create some root object and add it all to it because I see that it
again returns that object.. but I don't know where because I don't see what
calls it..
I imagine it two ways now... for example that there is some root object...
then you define a field at it and allocate a function to that you have in c
to that field... something like this root
alloc_field(root,val_id("myCFunc"),alloc_function(myCFunc,0,"myCFunc"));
and then I could probably call that function in neko....
if there is no root but everything gets passed only by returns then I
imagine that neko must call some function in c
that will then for example create an object and attach functions to it
and return it and then neko can call it from
that return value...
but this would mean that this first function that makes object with
binded c functions must be accessible to neko
in first place for which DECLARE_PRIM(createSomeObject, 0) is used?
but if this is the case how can I then call this in neko (remember I
have embedded the nekoVM
I am not making a dll binding..)
But if this works then I don't know how to reference to that function
... If I was making a dll binding I would use >>
var p = $loader.loadprim("[EMAIL PROTECTED]",0);
p();
>> as the example says but how do I include this , I tried
var p = $loader.loadprim("test",0); and
var p = $loader.loadprim("@test",0);
and it didn't work... If anyone knows any better he is welcome to
correct me as this is all based on imagination :)
best regards,
Janko
