NAME

       nbd_get_handshake_flags - see which handshake flags are supported

SYNOPSIS

        #include <libnbd.h>

        uint32_t nbd_get_handshake_flags (
                   struct nbd_handle *h
                 );

DESCRIPTION

       Return the state of the handshake flags on this handle.  When the handle has not yet
       completed a connection (see nbd_aio_is_created(3)), 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(3)), 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.

RETURN VALUE

       This call returns a bitmask of LIBNBD_HANDSHAKE_FLAG_* values.

ERRORS

       This function does not fail.

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

VERSION

       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:

        #define LIBNBD_HAVE_NBD_GET_HANDSHAKE_FLAGS 1
