api_cmd_head_init(9)

💅 api_cmd_head_init(9) — like, the Kernel API Manual page, bestie

okay so this is a page from the Kernel API Manual, section 9 — yes, the big brain kernel-functions section — and it's all about api_cmd_head_init. no cap, the name basically spoils it: we're setting the head of a chain in the hardware. iconic little function, honestly.

✨ NAME ✨

api_cmd_head_init — set the head of a chain in the HW 🎀

like, literally. that's the whole job. it puts the head where the hardware can see it. periodt.

🌸 SYNOPSIS 🌸

void api_cmd_head_init (struct hinic_api_cmd_chain *chain );

it returns nothing (void), it takes one pointer, and it gets straight to business. main character energy fr fr 💅

🦋 ARGUMENTS 🦋

• chain — the API CMD specific chain that you're setting the head for in HW. that's it. that's the one argument. give it the chain, it does the thing 🫶
