match_u64int(9)

okay so bestie, welcome to match_u64int(9) from the Kernel API Manual — this one is literally all about scanning a number in the given base from a substring_t, and it's giving “tiny parser helper” energy. 🎀

✨ NAME ✨

match_u64int — scans a number in the given base from a substring_t. no cap, that's the whole assignment. 💅

🛠️ SYNOPSIS 🛠️

int match_u64int (substring_t *s , u64 *result , int base );

🎀 ARGUMENTS 🎀

• s — the substring_t that's gonna get scanned, bestie. 🔍
• result — where the resulting u64 lands on success. 🫶
• base — the base to use when converting the string. iconic little number-base moment. 🔥

🌸 DESCRIPTION 🌸

Give it a substring_t and a base, and it attempts to parse that substring as a number in that base. that's it, that's the vibe. ✨

⭐ RETURN ⭐

On success, it sets result to the integer represented by the string and returns 0. if things go sideways, it returns -EINVAL or -ERANGE. periodt. 💀
