radcli_avp...ytes_by_num(3)

💅 NAME

radcli_avp_get_bytes_by_num — bestie, this one looks up an attribute by its legacy numeric ID and hands you the raw bytes of its first occurrence. That's the whole vibe. 🫶

The manual name is radcli_avp...ytes_by_num(3), from the Radius client library — yes the title's truncated, no we're not fixing it, it's iconic that way.

✨ SYNOPSIS

#include <radcli/>

int radcli_avp_get_bytes_by_num(
    const radcli_avp_list  *list,
    const radcli_ctx       *ctx,
    uint32_t                attrid,
    uint32_t                vendor,
    const void            **out,
    size_t                 *len
);

🎀 DESCRIPTION

Okay so the description section is lowkey just the vibes — the actual deets live in the parameters below, and honestly? Slay. Go read them, they ate. 👑

---

🌸 PARAMETERS

• list — the list you're searching. The main character of the search. 🔍
• ctx — a context with a dictionary loaded. No dictionary, no lookups, no cap.
• attrid — the attribute ID. Can be a PW_* constant, or a vendor type ID when vendor is non-zero. 💫
• vendor — the vendor PEN, or 0 for a standard attribute. Zero means "not a vendor thing", periodt.
• out — where the pointer to the value gets written. It's valid for list's lifetime (so don't go freeing things and acting surprised 😭). May be NULL.
• len — where the value's length in bytes gets written. May be NULL.

Bestie note: out and len are both allowed to be NULL, that's not a mistake, that's the API being generous. 💖

---

⭐ RETURN VALUE

• 0 — success, we love to see it ✨
• -1 — failure. That means no such attribute, or no occurrence of it. Not every search finds its person, and that's okay. 💀
