NAME

7

SYNOPSIS

9        #include <libnbd.h>
10
11        int nbd_connect_socket (struct nbd_handle *h, int sock);
12

DESCRIPTION

14       Pass a connected socket (file descriptor) which libnbd will talk to.
15       The program is responsible for connecting this somehow to an NBD
16       server.  Once the socket is passed to libnbd it is the responsibility
17       of libnbd.  Libnbd may read and write to it, set it to non-blocking,
18       etc., and will finally close it when the handle is closed.  The program
19       must no longer use the socket.
20

RETURN VALUE

22       If the call is successful the function returns 0.
