💅 iscsi_get_fl...ode_by_index(9) 💅

okay so real talk, bestie — welcome to the Kernel API Manual, section 9, and today's main character is iscsi_get_flashnode_by_index, aka the lil lookup function that's giving "I know a guy" energy for flashnode sessions. iykyk ✨

---

🎀 NAME 🎀

iscsi_get_flashnode_by_index — finds flashnode session entry by index. that's it, that's the whole job. lowkey iconic 🫶

---

✨ SYNOPSIS ✨

struct iscsi_bus_flash_session * iscsi_get_flashnode_by_index (struct
Scsi_Host *shost , uint32_t idx );

like, she takes two things and returns a whole pointer to a struct. no cap. 💅

---

🌸 ARGUMENTS 🌸

• shost — pointer to host data. your host. the one we're digging around in. 🦋
• idx — index to match. the number you're looking for, and she WILL find it (or not, see RETURN 👀).

---

💖 DESCRIPTION 💖

Finds the flashnode session object for the passed index.

that's the tea. you hand her an index, she goes and pulls up the flashnode session object that matches. she's not doing anything extra, she's not doing anything less — she's just doing exactly what she said on the tin. periodt. 👑

---

🔥 RETURN 🔥

• pointer to found flashnode session object on success ✨
• NULL on failure 😭

so like, vibe check your return value before you use it, bestie, because NULL is not a personality trait you want to inherit. 💀
