telling the user which subset of buf was just populated, and where
status is data, hole, or error. The signature may still need tweaking.
Or we may even want to let the user register a set of callbacks, where a
different callback is invoked for different chunk types:
set = nbd_callback_set_create(nbd, NBD_CMD_READ, opaque, default_cb,
default_error_cb);
nbd_callback_set_add(nbd, set, NBD_REPLY_TYPE_OFFSET_DATA, opaque, cb);
nbd_callback_set_add(nbd, set, NBD_REPLY_TYPE_OFFSET_HOLE, opaque, cb);
nbd_pread_callback(nbd, buf, count, offset, set, flags);
The idea of registering a set of callba...
