STRUCT DCCP_HDR_RESPONSE(9)

✨ struct dccp_hdr_response(9) ✨

okay so bestie, welcome to the Kernel API Manual page for struct dccp_hdr_response — literally the header that shows up when a DCCP connection is getting its whole initiation response moment. main character energy, fr fr 💅

---

🌸 NAME 🌸

struct dccp_hdr_response — the Connection initiation response header. that's it, that's the vibe 🎀

---

🦋 SYNOPSIS 🦋

here's the whole glow-up, exactly as it lives in the kernel:

struct dccp_hdr_response {
    struct dccp_hdr_ack_bits        dccph_resp_ack;
    __be32 dccph_resp_service;
};

no cap, that's the entire struct. two fields. iconic minimalism 💜

👑 Members 👑

bestie this is the member section, and the members are fully listed below in Description because the manpage said so and we do not argue with the manpage 🫶

🌈 Description 🌈

• dccph_resp_ack — the 48 bit Acknowledgment Number Subheader, and yes it's citing section (5.3), so it's official. 48 bits of pure acknowledgment realness ✨
• dccph_resp_service — this one echoes the Service Code that came in on a received DCCP-Request. it's giving "hey, I heard you, here's your code right back" 🪞💖

⭐ SEE ALSO ⭐

go read these next, i'm obsessed with all of them:

• Kernel file ./include/uapi/linux/dccp.h 🍓
• struct dccp_hdr(9)
• struct dccp_hdr_ext(9)
• struct dccp_hdr_request(9)
• struct dccp_hdr_ack_bits(9)
• struct dccp_hdr_reset(9)

lowkey important: those are struct references in section 9 of the manual, so don't go looking for them in section 1 like a silly goose 😭

okay that's the whole page, mwah 💋 this little cutie comes to you from ./include/uapi/linux and it's dated October 2026, and the page itself answers to the name struct dccp_hdr_response(9). go off, king 👑✨
