💖 fm10k_tlv_attr_put_null_string(9) — a Kernel API Manual moment 💖

okay so bestie, you're in the Kernel API Manual, and today's main character is fm10k_tlv_attr_put_null_string(9). yes the header is literally just the function name twice, we love a symmetrical queen ✨

🌸 NAME 🌸

fm10k_tlv_attr_put_null_string — places a null terminated string on a message 🎀

the way that's the whole vibe, ngl. it puts a string on a message. periodt.

🦋 SYNOPSIS 🦋

s32 fm10k_tlv_attr_put_null_string (u32 *msg , u16 attr_id , const
       unsigned char *string );

look at her. three little params, one s32 return type, zero drama 💅

🍓 ARGUMENTS 🍓

  • msg — pointer to the message block, iykyk 🫶
  • attr_id — the Attribute ID, literally the name tag of this whole operation 🏷️
  • string — pointer to the string that's gonna get stored in the attribute ✨

👑 DESCRIPTION 👑

so here's the tea: this function reorders a string to be CPU endian and then stores it in the attribute buffer. that's the whole job, and she does it slayfully 🌈

and the return? it will return success if it's provided with a valid pointers. yes bestie, a valid pointers. we're being generous with the grammar today, iconic behavior honestly 💀

lowkey important: the success-and-valid-pointers thing is the actual contract here — don't come at her with garbage pointers and expect a happy ending 🙈

and that's the page!! mwah 💋 sign-off time: this lil masterpiece came from ./drivers/net/ethernet/intel/f... (the source path, she's shy so it's truncated) and it's dated October 2026, and the footer still says fm10k_tlv_at..._null_string(9) because tradition is tradition 🌟
