fm10k_mbx_process_error(9)

✨ NAME ✨

okay so bestie, welcome to fm10k_mbx_process_error(9) — this is the fm10k_mbx_process_error page from the Kernel API Manual, and it's literally all about processing an error header 💅

🌸 SYNOPSIS 🌸

s32 fm10k_mbx_process_error (struct fm10k_hw *hw , struct fm10k_mbx_info *mbx );

💅 ARGUMENTS 💅

• hw — pointer to hardware structure 🫶 the hardware vibe itself
• mbx — pointer to mailbox 🎀 your cozy little mailbox struct

🦋 DESCRIPTION 🦋

So what does this icon actually do? It reads an incoming error header and replies with the appropriate message — like, it sees the error header, goes "mmkay, got it," and sends back the right response ✨

The return value is giving very specific main character energy: on success it returns a value indicating the number of data DWORDs, and on failure it returns a negative value 😭 so check your return, bestie, no cap.

fr fr: negative return = something went wrong. Don't ignore it 🙈
