rc_avpair_get_attr(3)

💖 rc_avpair_get_attr — from the Radius client library 💖

okay so bestie, welcome to rc_avpair_get_attr(3), one of the lil helper functions hanging out in the radcli family. she's from the Radius client library and she is, ngl, extremely straightforward. let's get into it 🫶

---

✨ NAME ✨

rc_avpair_get_attr —

and that's it. that's the whole description. the description slot is empty. she said "my name is enough" and honestly? main character energy. 💅

---

🌸 SYNOPSIS 🌸

#include <radcli/radcli.h>

void rc_avpair_get_attr(
    VALUE_PAIR  *vp,
    unsigned    *type,
    unsigned    *id
);

so you pull in <radcli/radcli.h> and then you call this with three things. that's the whole vibe check. ✨

---

🦋 DESCRIPTION 🦋

lowkey the entire job description here is one sentence: this function gets the attribute ID and the type of the attribute value-pair you hand it.

that's it. no side quests. no hidden lore. she reads the pair, she tells you the type and the id. periodt. 👑

---

🎀 PARAMETERS 🎀

• vp — a pointer to a VALUE_PAIR structure. yes, the one you want the deets from. hand her the pointer and she'll do the rest 💜
• type — The attribute type, of type rc_attr_type. this is an out-param situation, she's gonna write the type back into it for you.
• id — The attribute identifier, of type rc_attr_id. same deal, she fills this one in with the id.

---

🧚 STRUCTURES 🧚

⚠️ bestie, listen to me very carefully: Avoid using this structure directly. Use the rc_avpair_get_ functions.

like fr fr, do not go poking around in there yourself. she's got helper functions for a reason. the struct is giving "look but don't touch" 💀

struct rc_value_pair {
  char                   name[RC_NAME_LENGTH+1];      // attribute name if known.
  uint64_t               attribute; // attribute numeric value of type rc_attr_id including vendor; use VENDOR() and ATTRID() to separate.
  rc_attr_type           type;      // attribute type.
  uint32_t               lvalue;    // attribute value if type is PW_TYPE_INTEGER, PW_TYPE_DATE or PW_TYPE_IPADDR.
  char                   strvalue[AUTH_STRING_LEN+1];  // contains attribute value in other cases.
  struct rc_value_pair  *next;
  char                   pad[32];       // unused pad
};

okay breaking it down because I love you:

• name[RC_NAME_LENGTH+1] — the attribute name, if it's known. the +1 is for the null terminator, as always, we love a null terminator 🥰
• attribute — the attribute numeric value, of type rc_attr_id, and yes it includes the vendor. use VENDOR() and ATTRID() to separate them out. iykyk 🫶
• type — the attribute type, of type rc_attr_type. hi again bestie.
• lvalue — the attribute value if the type is PW_TYPE_INTEGER, PW_TYPE_DATE or PW_TYPE_IPADDR. those three. exactly those three.
• strvalue[AUTH_STRING_LEN+1] — contains the attribute value in other cases. so like, everything that isn't those three types up there ☝️
• next — pointer to the next rc_value_pair. it's a linked list bestie, we're linking 🦋
• pad[32] — unused pad. literally just vibes. she's sitting there taking up space and we respect her for it ✨
