NAME

       nbd_aio_connect_vsock - connect to the NBD server over AF_VSOCK socket

SYNOPSIS

        #include <libnbd.h>

        int nbd_aio_connect_vsock (struct nbd_handle *h,
                                   uint32_t cid, uint32_t port);

DESCRIPTION

       Begin connecting to the NBD server over the "AF_VSOCK" protocol to the server "cid:port".
       Parameters behave as documented in nbd_connect_vsock(3).

       You can check if the connection is still connecting by calling nbd_aio_is_connecting(3),
       or if it has connected to the server and completed the NBD handshake by calling
       nbd_aio_is_ready(3), on the connection.

RETURN VALUE

       If the call is successful the function returns 0.

ERRORS

       On error "-1" is returned.

       Refer to "ERROR HANDLING" in libnbd(3) for how to get further details of the error.

HANDLE STATE

       The handle must be newly created, otherwise this call will return an error.

VERSION

       If you need to test if this function is available at compile time check if the following
       macro is defined:
