NAME

6       nbd_set_uri_allow_tls - set the allowed TLS settings in NBD URIs
7

SYNOPSIS

9        #include <libnbd.h>
10
11        int nbd_set_uri_allow_tls (struct nbd_handle *h, int tls);
12

DESCRIPTION

14       Set which TLS settings are allowed to appear in NBD URIs.  The default
15       is to allow either non-TLS or TLS URIs.
16
17       The "tls" parameter can be:
18
19       "LIBNBD_TLS_DISABLE"
20           TLS URIs are not permitted, ie. a URI such as "nbds://..."  will be
21           rejected.
22
23       "LIBNBD_TLS_ALLOW"
24           This is the default.  TLS may be used or not, depending on whether
25           the URI uses "nbds" or "nbd".
26
27       "LIBNBD_TLS_REQUIRE"
28           TLS URIs are required.  All URIs must use "nbds".
