match_number(9)

✨ match_number(9) ✨

okay so this is a page from the Kernel API Manual, and it's literally about match_number — the lil function that scans a number in whatever base you want out of a substring_t 🎀

---

🌸 NAME 🌸

match_number — scan a number in the given base from a substring_t 💅

🦋 SYNOPSIS 🦋

int match_number (substring_t *s , int *result , int base );

💖 ARGUMENTS 💖

• s — the substring that's about to get scanned, bestie. it's giving "raw material" ✨
• result — where the resulting integer lands if everything slays 🎀
• base — the base to use when converting the string, iykyk 👑

🌈 DESCRIPTION 🌈

so you hand it a substring_t and a base, and it attempts to parse that substring as a number in that base. that's the whole vibe fr fr 🫶

⭐ RETURN ⭐

on success it sets result to the integer that the string represents and returns 0 — iconic, no notes 💅

on failure it returns -EINVAL or -ERANGE. so like, if you see one of those, something did not eat 😭

ngl, check your return value. 0 means slay, negative means the parse did not survive the vibe check 💀
