💅 radcli_avp_...cstr_by_num(3) — the radcli girlies' guide

okay so bestie, welcome to the radcli_avp_...cstr_by_num page from the Radius client library (that's the manual section, mwah) 💖 this one's a little lookup queen and she is lowkey iconic.

✨ NAME ✨

radcli_avp_get_cstr_by_num — look up an attribute by its legacy numeric ID and read its first occurrence as a NUL-terminated string. that's it, that's the vibe 🎀

🌸 SYNOPSIS 🌸

#include <radcli/>

const char * radcli_avp_get_cstr_by_num(
    const radcli_avp_list  *list,
    const radcli_ctx       *ctx,
    uint32_t                attrid,
    uint32_t                vendor
);

like yes, she takes four things, she gives you a const char *, no cap 🫶

🦋 DESCRIPTION 🦋

bestie this is the function for when you've got a legacy numeric attribute ID and you want the first occurrence of it as a NUL-terminated string. the parameters are right below, keep scrolling ✨

⭐ PARAMETERS ⭐

  • list — the list to search. she's gonna go through it, respectfully 🔍
  • ctx — a context with a dictionary loaded. no dictionary, no vibes, fr fr 📖
  • attrid — the attribute ID (a PW_* constant, or a vendor type ID when vendor is non-zero). yep, either/or, depending on the vendor situation 💅
  • vendor — the vendor PEN, or 0 for a standard attribute. 0 means "just a normal one, nothing fancy" 🍓

👑 RETURN VALUE 👑

a pointer valid for list's lifetime — she's owned by list, never freed by the caller, okay? do NOT free her, that's not your job, periodt 🙈

and she returns NULL if:

  • no such attribute is defined 😭
  • no occurrence exists 💀
  • or as radcli_avp_get_cstr() (embedded NUL byte, or invalid UTF-8 for a RADCLI_TYPE_TEXT attribute) 🔥

so like, check for NULL before you do anything unhinged with that pointer, iykyk 🧚
