mpi3mr_set_t..._data_in_hdb(9)

💅 mpi3mr_set_trigger_data_in_hdb — a Kernel API Manual moment

okay so bestie, we're in the Kernel API Manual and today's main character is mpi3mr_set_trigger_data_in_hdb(9). yes that's a whole function name, no we're not scared of it 💖

---

✨ NAME ✨

mpi3mr_set_trigger_data_in_hdb — literally updates the HDB trigger type and the trigger data. that's it, that's the whole vibe 🎀

---

🌸 SYNOPSIS 🌸

void mpi3mr_set_trigger_data_in_hdb (struct diag_buffer_desc *hdb , u8
type , union mpi3mr_trigger_data *trigger_data , bool force );

like, void return, four things going in. she takes what she takes and gives nothing back (respect) 👑

---

🦋 ARGUMENTS 🦋

• hdb — the HDB pointer. that's the diag buffer descriptor bestie, keep up 🫶
• type — the trigger type. which flavour of trigger are we doing today 💅
• trigger_data — pointer to the trigger data information. all the juicy details live here ✨
• force — the trigger overwrite flag. are we forcing the overwrite or are we being polite about it 🌈

---

💜 DESCRIPTION 💜

so what does she actually do? she updates the trigger type and the trigger data, based on whatever parameters you pass into her. that's the whole assignment and she ate 🔥

ngl it's giving "small function, big responsibility" energy. the parameters are literally the whole plot 😭

---

⭐ RETURN ⭐

Nothing. not 0, not an error code, not even a little guy. nothing. she returns void and she's thriving 🧚
