SYNOPSIS

9        #include <libnbd.h>
10
11        int nbd_aio_connect_tcp (struct nbd_handle *h,
12                                 const char *hostname,
13                                 const char *port);

DESCRIPTION

16       Begin connecting to the NBD server listening on "hostname:port".
17       Parameters behave as documented in nbd_connect_tcp(3).
18
19       You can check if the connection is still connecting by calling
20       nbd_aio_is_connecting(3), or if it has connected to the server and
21       completed the NBD handshake by calling nbd_aio_is_ready(3), on the
22       connection.
23

RETURN VALUE

25       If the call is successful the function returns 0.
26
