       nbd_get_handshake_flags - see which handshake flags are supported


        #include <libnbd.h>

        unsigned nbd_get_handshake_flags (struct nbd_handle *h);


       Return the state of the handshake flags on this handle.  When the handle has not yet
       completed a connection (see "nbd_aio_is_created"), this returns the flags that the client
       is willing to use, provided the server also advertises those flags.  After the connection
       is ready (see "nbd_aio_is_ready"), this returns the flags that were actually agreed on
       between the server and client.  If the NBD protocol defines new handshake flags, then the
       return value from a newer library version may include bits that were undefined at the time
       of compilation.


       This call returns a bitmask.


       This function does not fail.


       This function first appeared in libnbd 1.2.

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



       nbd_set_handshake_flags(3), nbd_get_protocol(3), nbd_aio_is_created(3),
       nbd_aio_is_ready(3), nbd_create(3), libnbd(3).
