nbd_aio_is_processing - check if the connection is processing a command
#include <libnbd.h> int nbd_aio_is_processing (struct nbd_handle *h);
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.
This call returns a boolean value.
This function does not fail.
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
nbd_aio_is_ready(3), nbd_create(3), libnbd(3).
