fm10k_tlv_at...ut_le_struct(9)

💅 fm10k_tlv_at...ut_le_struct — Kernel API Manual, bestie edition ✨

okay so picture this: you're deep in the kernel, you've got a message block, and you need a little endian struct to live inside one of its attributes. that's literally this function. welcome 🫶

🌸 NAME 🌸

fm10k_tlv_attr_put_le_struct — Store little endian structure in message 💖

no fr that's the whole gig. it puts a le struct in a message. slay.

---

⭐ SYNOPSIS ⭐

s32 fm10k_tlv_attr_put_le_struct (u32 *msg , u16 attr_id , const void
       *le_struct , u32 len );

she takes four things and gives you back an s32. iconic signature tbh 👑

---

🎀 ARGUMENTS 🎀

• msg — Pointer to message block. like, the message block itself. the whole vibe container 🦋
• attr_id — Attribute ID. this is the label on the lil attribute drawer you're stuffing your struct into
• le_struct — Pointer to structure to be written. the actual little endian struct, ready for its moment ✨
• len — Size of le_struct. how much of the thing we're writing. keep reading, there's a catch 👀

---

🔥 DESCRIPTION 🔥

This function will place a little endian structure value in a message attribute. periodt 💅

The function will return success provided that all pointers are valid and len is a non-zero multiple of 4.

okay so lowkey the vibe check here is real: every pointer has to be valid (no nulls, bestie, i'm begging) and len has to be nonzero and a multiple of 4. miss any of those and no success for you 😭 it's giving "read the requirements before you ship" energy.
