[Xen-API] problem in c binding xen_event_register / xen_string_set

["Dube, Lutz" <Lutz.Dube@xxxxxxxxxxxxxxxxxxx>]

Hello,

 

I have a problem using the xen-api c bindings. I want to register some classes

to deliver events. 

If I call xen_event_register(session, stringset), I get a "Error: 2

TRANSPORT_FAULT 52", if stringset only contains one class. If the string set

contains two classes, it seems that only the first class is taken into

account. I think the error is in the c binding, because using the python

interface it works fine.

I seems to be a common problem passing xen_string_set objects to xend and not

a special one of xen_event_register.

 

This is my c code:

 

    xen_string_set *s = xen_string_set_alloc(2);

    s->contents[0] = xen_strdup_("VIF");

    s->contents[1] = xen_strdup_("VBD");

    X_C(xen_event_register(session, s));

    xen_string_set_free(s);

 

 

Here is the XML-Output of the second try:

 

---Data to server: -----------------------

    <methodName>event.register</methodName>
