Hi,
I want to know how to use XS_WATCH, i assume first i do as fellow:
struct xsd_sockmsg msg;
msg.type=XS_WATCH;
write_request((char*)msg, sizeof(msg));
write_request(path, path_length);
struct evtchn_send event;
event.port=xenstore_event;
hypercall_event_channel_op(EVTCHNOP_send, &event);
after that, what should i do? does it just block in hypercall_event_channel_op()
until the value in xenstore specified by path is changed , and when it return ,i
can read the changed value by the responds msg?
