# nbd\_stats\_bytes\_received(3)

statistics of bytes received over connection so far

## NAME

nbd\_stats\_bytes\_received - statistics of bytes received over connection so far

## SYNOPSIS

```
 #include <libnbd.h>
 uint64_t nbd_stats_bytes_received (
            struct nbd_handle *h
          );
```

## DESCRIPTION

Return the number of bytes that the client has received from the server.

This tracks the plaintext bytes utilized by the NBD protocol; it may differ from the number of bytes actually received over the connection, particularly when TLS is in use.

## RETURN VALUE

This call returns a counter.

## ERRORS

This function does not fail.

The following parameters must not be NULL: `"h"`. For more information see "Non-NULL parameters" in [**libnbd**(3)](/libnbd/3.md).

## VERSION

This function first appeared in libnbd 1.16.

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

```
 #define LIBNBD_HAVE_NBD_STATS_BYTES_RECEIVED 1
```
