NAME

6       nbd_set_request_structured_replies - control use of structured replies
7

SYNOPSIS

9        #include <libnbd.h>
10
11        int nbd_set_request_structured_replies (struct nbd_handle *h,
12                                                bool request);
13

DESCRIPTION

15       By default, libnbd tries to negotiate structured replies with the
16       server, as this protocol extension must be in use before
17       nbd_can_meta_context(3) or nbd_can_df(3) can return true.  However, for
18       integration testing, it can be useful to clear this flag rather than
19       find a way to alter the server to fail the negotiation request.
20
