__i40e_pf_next_vsi(9)

💫 NAME 💫

ok so bestie, this is the Kernel API Manual entry for __i40e_pf_next_vsi — and what it does is get next valid VSI. that's it. that's the whole vibe. she finds the next VSI that actually exists 🎀

---

✨ SYNOPSIS ✨

struct i40e_vsi * __i40e_pf_next_vsi (struct i40e_pf *pf , int *idx );

like, literally the whole signature. no cap. 🦋

---

🌸 ARGUMENTS 🌸

• pf — pointer to the PF struct. she's the main character here, the big one you're digging through 🔥
• idx — pointer to the start position number. this is where you tell her to start looking, and she'll update it for you as she goes 💅

---

🧚 DESCRIPTION 🧚

ok so picture this: you hand her a pf, you hand her an idx, and she goes digging through the pf->vsi array looking for the next non-NULL VSI pointer. when she finds one, she returns it — and she updates the idx position too, so you know where she landed 👑

and if there's literally nothing there to find? she returns NULL. no VSI found, no VSI returned, no drama. periodt. 💀

ngl, always check for that NULL before you go dereferencing it, bestie — that's just good manners 🫶
