9 #include <libnbd.h>
10
11 int nbd_set_uri_allow_transports (
12 struct nbd_handle *h, uint32_t mask
13 );
14
16 Set which transports are allowed to appear in NBD URIs. The default is
17 to allow any transport.
18
19 The "mask" parameter may contain any of the following flags ORed
20 together:
21
22 "LIBNBD_ALLOW_TRANSPORT_TCP" = 0x1
23 "LIBNBD_ALLOW_TRANSPORT_UNIX" = 0x2
24 "LIBNBD_ALLOW_TRANSPORT_VSOCK" = 0x4
25
26 For convenience, the constant "LIBNBD_ALLOW_TRANSPORT_MASK" is
27 available to describe all transports recognized by this build of
28 libnbd. A future version of the library may add new flags.
29
31 If the call is successful the function returns 0.
32
34 On error -1 is returned.
35
36 Refer to "ERROR HANDLING" in libnbd(3) for how to get further details
37 of the error.

39 The following parameters must not be NULL: "h". For more information
40 see "Non-NULL parameters" in libnbd(3).
41
43 The handle must be newly created, otherwise this call will return an
44 error.

47 This function first appeared in libnbd 1.2.

49 If you need to test if this function is available at compile time check
50 if the following macro is defined:
51
52 #define LIBNBD_HAVE_NBD_SET_URI_ALLOW_TRANSPORTS 1
53
55 nbd_connect_uri(3), nbd_create(3), nbd_set_uri_allow_tls(3), libnbd(3).
