NAME

       nbd_aio_is_processing - check if the connection is processing a command

SYNOPSIS

        #include <libnbd.h>

        int nbd_aio_is_processing (
              struct nbd_handle *h
            );

DESCRIPTION

       Return true if this connection is connected to the NBD server, the handshake has
       completed, and the connection is processing commands (either writing out a request or
       reading a reply).

       Note the ready state (nbd_aio_is_ready(3)) is not included.  In the ready state commands
       may be in flight (the server is processing them), but libnbd is not processing them.

RETURN VALUE

       This call returns a boolean value.

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 1.0.

       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_PROCESSING 1
