NAME

       nbd_set_socket_activation_name - set the socket activation name

SYNOPSIS

        #include <libnbd.h>

        int nbd_set_socket_activation_name (
              struct nbd_handle *h, const char *socket_name
            );

DESCRIPTION

       When running an NBD server using nbd_connect_systemd_socket_activation(3) you can
       optionally name the socket.  Call this function before connecting to the server.

       Some servers such as qemu-storage-daemon(1) can use this information to associate the
       socket with a name used on the command line, but most servers will ignore it.  The name is
       passed through the "LISTEN_FDNAMES" environment variable.

       The parameter "socket_name" can be a short alphanumeric string.  If it is set to the empty
       string (also the default when the handle is created) then the name "unknown" will be seen
       by the server.

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.

       The following parameters must not be NULL: "h", "socket_name".  For more information see
       "Non-NULL parameters" in libnbd(3).

       nbd_set_socket_activation_name can be called when the handle is in the following state:
