NAME

6       nbd_set_uri_allow_transports - set the allowed transports in NBD URIs
7

SYNOPSIS

9        #include <libnbd.h>
10
11        int nbd_set_uri_allow_transports (
12              struct nbd_handle *h, uint32_t mask
13            );
14

DESCRIPTION

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.
