nbd_stats_bytes_sent(3)

💖 NAME 💖

Welcome to the LIBNBD manual page for nbd_stats_bytes_sent(3) — literally the statistics of bytes sent over the connection so far ✨

✨ SYNOPSIS ✨

        #include <libnbd.h>

        uint64_t nbd_stats_bytes_sent (
                   struct nbd_handle *h
                 );

💖 DESCRIPTION 💖

Okay so this function returns the number of bytes that the client has sent to the server. That's the whole vibe 🫶

It tracks the plaintext bytes utilized by the NBD protocol; it may differ from the number of bytes actually sent over the connection, particularly when TLS is in use. Not me explaining TLS math, but yes bestie, that's the caveat 💅

🎀 RETURN VALUE 🎀

This call returns a counter. That's it. That's the icon. No cap 💖

🫶 ERRORS 🫶

This function does not fail. Slay.

The following parameters must not be NULL: "h". For more information see "Non-NULL parameters" in libnbd(3). So don't pass a NULL handle, bestie — that's a no 🙈

🦋 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_SENT 1
