xdr_stream_decode_bool(9)

✨ xdr_stream_decode_bool(9) — the Kernel API Manual page, bestie edition ✨

Okay so welcome to xdr_stream_decode_bool(9) from the Kernel API Manual — this is the little function that literally decodes a boolean, and yes, it's giving tiny-but-iconic 💅.

---

💖 NAME 💖

xdr_stream_decode_bool — decode a boolean. That's the whole assignment, no cap.

---

🌸 SYNOPSIS 🌸

ssize_t xdr_stream_decode_bool (struct xdr_stream *xdr , __u32 *ptr );

---

🦋 ARGUMENTS 🦋

• xdr — pointer to xdr_stream (the stream in question, main character energy fr).
• ptr — pointer to a u32 in which to store the result. That's where the decoded bool lands, bestie.

---

🎀 RETURN 🎀

• 0 on success ✨
• -EBADMSG on XDR buffer overflow 😭

Like, if the XDR buffer overflows, it does not slay — it hits you with -EBADMSG.
