NAME

       nbd_set_uri_allow_tls - set the allowed TLS settings in NBD URIs

SYNOPSIS

        #include <libnbd.h>

        int nbd_set_uri_allow_tls (struct nbd_handle *h, int tls);

DESCRIPTION

       Set which TLS settings are allowed to appear in NBD URIs.  The default is to allow either
       non-TLS or TLS URIs.

       The "tls" parameter can be:

       "LIBNBD_TLS_DISABLE"
           TLS URIs are not permitted, ie. a URI such as "nbds://..."  will be rejected.

       "LIBNBD_TLS_ALLOW"
           This is the default.  TLS may be used or not, depending on whether the URI uses "nbds"
           or "nbd".

       "LIBNBD_TLS_REQUIRE"
           TLS URIs are required.  All URIs must use "nbds".

RETURN VALUE

       If the call is successful the function returns 0.

ERRORS

       On error "-1" is returned.

       Refer to "ERROR HANDLING" in libnbd(3) for how to get further details of the error.

       The following parameters must not be NULL: "h".  For more information see "Non-NULL
       parameters" in libnbd(3).

HANDLE STATE

       macro is defined:
