NAME

       nbd_aio_connect_systemd_socket_activation - connect using systemd socket activation

SYNOPSIS

        #include <libnbd.h>

        int nbd_aio_connect_systemd_socket_activation (struct nbd_handle *h,
                                                       char **argv);

DESCRIPTION

       Run the command as a subprocess and begin connecting to it using systemd socket
       activation.  Parameters behave as documented in nbd_connect_systemd_socket_activation(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.
