💅 qmi_calc_min_msg_len(9) — bestie’s Kernel API Manual moment

okay so this is the qmi_calc_min_msg_len(9) page from the Kernel API Manual, and it’s giving “tiny utility that tells you how short a QMI message can be.” no cap, that’s the whole vibe. 🎀

🌸 NAME 🌸

qmi_calc_min_msg_len — literally calculates the minimum length of a QMI message. ✨

✨ SYNOPSIS ✨

int qmi_calc_min_msg_len (const struct qmi_elem_info *ei_array , int
       level );

bestie, that’s the signature, and we are not changing one character of it. periodt. 💅

🫶 ARGUMENTS 🫶

• ei_array — the struct info array describing the structure. it’s the blueprint, the little descriptor squad. 🗺️
• level — the level to identify the depth of the nested structures. basically the depth-checker for your nested-structure situation. 🌀

🔥 RETURN 🔥

the expected minimum length of the QMI message, or 0 on error. that’s it. that’s the return. 😌
