xdr_stream_..._opaque_auth(9)

💅 xdr_stream_encode_opaque_auth(9) 💅

okay so bestie, welcome to the Kernel API Manual — this page is all about xdr_stream_encode_opaque_auth, and it’s giving “tiny XDR encoder with main character energy” ✨

---

🎀 NAME 🎀

xdr_stream_encode_opaque_auth — encode struct opaque_auth (RFC5531 S8.2) 💖

---

✨ SYNOPSIS ✨

ssize_t xdr_stream_encode_opaque_auth (struct xdr_stream *xdr , u32
flavor , void *body , unsigned int body_len );

---

🫶 ARGUMENTS 🫶

• xdr — pointer to xdr_stream
• flavor — verifier flavor to encode
• body — content of body to encode
• body_len — length of body to encode

---

💅 DESCRIPTION 💅

Return values, bestie — this is the vibe check you cannot skip:

• On success, returns length in bytes of XDR buffer consumed.
• -EBADMSG on XDR buffer overflow.
• -EMSGSIZE if the size of body exceeds 400 octets.
