NAME¶

nbd_aio_is_negotiating - check if connection is ready to send handshake option

SYNOPSIS¶

 #include <libnbd.h>
 int nbd_aio_is_negotiating (struct nbd_handle *h);

DESCRIPTION¶

Return true if this connection is ready to start another option negotiation command while handshaking with the server. An option command will move back to the connecting state (see nbd_aio_is_connecting(3)). Note that this state cannot be reached unless requested by nbd_set_opt_mode(3), and even then it only works with newstyle servers; an oldstyle server will skip straight to nbd_aio_is_ready(3).

RETURN VALUE¶

This call returns a boolean value.

ERRORS¶

This function does not fail.

VERSION¶

This function first appeared in libnbd 1.4.

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

 #define LIBNBD_HAVE_NBD_AIO_IS_NEGOTIATING 1

SEE ALSO¶

nbd_aio_is_connecting(3), nbd_aio_is_ready(3), nbd_create(3), nbd_set_opt_mode(3), libnbd(3).
