pldm_move_fw_offset(9)

💅 pldm_move_fw_offset(9) — like, the Kernel API Manual page, bestie

okay so you found the man page for pldm_move_fw_offset and honestly? it's a little baby function with main character energy. it does exactly one thing and it does it slayfully: it moves the current firmware offset forward. that's it. that's the whole vibe. periodt. ✨

🌸 NAME 🌸

pldm_move_fw_offset — Move the current firmware offset forward 🦋

---

🎀 SYNOPSIS 🎀

int pldm_move_fw_offset (struct pldmfw_priv *data , size_t bytes_to_move
);

yes bestie, that's the whole signature, no cap. it hands you back an int and takes two things. let's get into them 💖

---

✨ ARGUMENTS ✨

• data — pointer to private data 🤫 like, the internal stuff, the private data, the iykyk data. you don't poke at it, you just pass it along.
• bytes_to_move — number of bytes to move the offset forward by 🦋 that's literally it, that's the number, it's a size_t, she's doing her best.

---

💜 DESCRIPTION 💜

okay so here's the tea ☕: this function first checks that there's enough space past the current offset, and then it moves the offset forward by bytes_to_move. that's the whole flow. check first, move second. it's giving responsible. it's giving "i looked before i leapt." we love a cautious icon 👑

so like, the order actually matters here — it's not just gonna blindly yeet the offset forward and hope for the best. it verifies there's room, and only then does the moving. slay 🌈

---

🔥 RETURN 🔥

• zero on success 🎉 (yes, 0, the good ending, the happy little number)
• -EFAULT if the image is too small to fit the expected length 😭 the image said "i have no room" and the function said "okay, -EFAULT then."

ngl if you get -EFAULT here, your image is too small for the expected length. that's the whole warning. don't shoot the messenger 💀
