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 (
12              struct nbd_handle *h, int tls
13            );
14

DESCRIPTION

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