hdm_request_netinfo(9)

💖 hdm_request_netinfo — request network information 💖

okay so this is a page from the Kernel API Manual (yes, the kernel has lore, we're reading it, bestie 🎀) and it's about hdm_request_netinfo, which is honestly such a main character function name. let's get into it ✨

---

🌸 SYNOPSIS 🌸

void hdm_request_netinfo (struct most_interface *iface , int channel ,
void (*on_netinfo)(struct most_interface *, unsigned char, unsigned char
*) );

literally that's the whole signature, no notes 💅 (void return, so she doesn't give anything back — she just does things)

---

🦋 ARGUMENTS 🦋

• iface — pointer to interface. that's it, that's the description, it's giving minimalism 🫶
• channel — channel ID. which channel, bestie. you tell me.
• on_netinfo — -- undescribed -- 😭 not the docs just leaving it blank. iconic of them honestly. no cap, the original page literally has nothing here, so i'm not gonna invent lore for it 🙈

---

✨ DESCRIPTION ✨

so what does she do? this one gets used as a trigger — it sets up the link status timer, and that timer polls for the NI state of the INIC every 2 seconds. 🔥

that's the whole vibe: call this, timer goes brrr, every 2 seconds it checks the NI state of the INIC. periodt. 💜

ngl if you're touching MOST/HDM driver code, read link_stat_timer_handler(9) and wq_netinfo(9) next — they're the actual squad that hangs out with this timer situation. 🌈

kisses bestie, that's the page 💖 this little cutie came out of ./drivers/most and the manual's dated October 2026 — so yeah, we're reading from the future, and she still slays ✨🎀🦋
