💅 radcli_attr_def_oid(3) 💅

okay so this one comes from the Radius client library manual, and it's all about rendering an attribute definition's RFC 6929 §2.7 OID notation. slay. ✨

🌸 NAME 🌸

radcli_attr_def_oid — Render an attribute definition's RFC 6929 §2.7 OID notation.

✨ SYNOPSIS ✨

#include <radcli/>

int radcli_attr_def_oid(
    const radcli_attr_def  *def,
    char                   *buf,
    size_t                  buflen
);

💖 DESCRIPTION 💖

No extra lore here, bestie — the whole vibe is rendering that OID notation. The important deets are in the parameters and return value below. 🫶

🎀 PARAMETERS 🎀

• def — an attribute definition from radcli_dict_lookup() or a sibling. 👑
• buf — destination buffer; may be NULL if buflen is 0. 🪄
• buflen — size of buf in bytes. 📏

🔥 RETURN VALUE 🔥

the number of characters the OID text would occupy, excluding the terminating null, as with snprintf(); negative if def is NULL.

So yeah — it's giving snprintf() energy: you get the character count the OID text would take up, not counting the terminating null, and if def is NULL the return is negative. 💀
