NAME

6       nbd_aio_connect_systemd_socket_activation - connect using systemd
7       socket activation
8

SYNOPSIS

10        #include <libnbd.h>
11
12        int nbd_aio_connect_systemd_socket_activation (
13              struct nbd_handle *h, char **argv
14            );
15

DESCRIPTION

17       Run the command as a subprocess and begin connecting to it using
18       systemd socket activation.  Parameters behave as documented in
19       nbd_connect_systemd_socket_activation(3).
20
21       You can check if the connection attempt is still underway by calling
22       nbd_aio_is_connecting(3).  If nbd_set_opt_mode(3) is enabled, the
23       connection is ready for manual option negotiation once
24       nbd_aio_is_negotiating(3) returns true; otherwise, the connection
25       attempt will include the NBD handshake, and is ready for use once
26       nbd_aio_is_ready(3) returns true.
27
