NAME

6       nbd_aio_connect_uri - connect to an NBD URI
7

SYNOPSIS

9        #include <libnbd.h>
10
11        int nbd_aio_connect_uri (
12              struct nbd_handle *h, const char *uri
13            );
14

DESCRIPTION

16       Begin connecting to the NBD URI "uri".  Parameters behave as documented
17       in nbd_connect_uri(3).
18
19       You can check if the connection attempt is still underway by calling
20       nbd_aio_is_connecting(3).  If nbd_set_opt_mode(3) is enabled, the
21       connection is ready for manual option negotiation once
22       nbd_aio_is_negotiating(3) returns true; otherwise, the connection
23       attempt will include the NBD handshake, and is ready for use once
24       nbd_aio_is_ready(3) returns true.
25

RETURN VALUE

27       If the call is successful the function returns 0.
