fs_umode_to_dtype(9)

💅 fs_umode_to_dtype(9) — the Kernel API Manual moment

okay so bestie, we're in the kernel API manual (9 section, that's the kernel one, iykyk) and today's main character is fs_umode_to_dtype. she does exactly one thing and she does it slayfully.

---

✨ NAME ✨

fs_umode_to_dtype — file mode to dirent file type. that's it. that's the whole job. 🎀

---

🦋 SYNOPSIS 🦋

unsigned char fs_umode_to_dtype (umode_t mode );

literally just hand her a mode and she hands you back an unsigned char. no drama, no side quests. 💖

---

🌸 ARGUMENTS 🌸

• mode — the file mode you wanna convert. that's the input, bestie, that's what you're feeding her. 🍓

---

👑 DESCRIPTION 👑

so like, this function converts the file mode value to the directory entry type (DT_*). that's the vibe. mode in, DT_* out. she's the translator in the group chat between "file mode" and "dirent type" and honestly? she never misses. 💅✨

---

🧚 CONTEXT 🧚

any context. any. not me being flexible about it — she genuinely does not care where you call her from. 🌈

---

⭐ RETURN ⭐

here's the whole menu of what she might hand back:

• DT_UNKNOWN — unknown type 🙈
• DT_FIFO — FIFO
• DT_CHR — character device
• DT_DIR — directory
• DT_BLK — block device
• DT_REG — regular file
• DT_LNK — symbolic link
• DT_SOCK — local-domain socket

eight whole options and every single one of them is valid. no cap. 🔥
