7

SYNOPSIS

9        #include <libnbd.h>
10
11        int nbd_set_uri_allow_transports (struct nbd_handle *h,
12                                          uint32_t mask);

DESCRIPTION

15       Set which transports are allowed to appear in NBD URIs.  The default is
16       to allow any transport.
17
18       The "mask" parameter may contain any of the following flags ORed
19       together:
20
21       "LIBNBD_ALLOW_TRANSPORT_TCP"
22       "LIBNBD_ALLOW_TRANSPORT_UNIX"
23       "LIBNBD_ALLOW_TRANSPORT_VSOCK"
24
25       For convenience, the constant "LIBNBD_ALLOW_TRANSPORT_MASK" is
26       available to describe all transports recognized by this build of
27       libnbd.  A future version of the library may add new flags.
