rc_avpair_next(3)

💖 rc_avpair_next 💖

okay bestie, so we're in the radcli radius client library manual, page rc_avpair_next(3), and honestly? this one is a little cutie. it walks the linked list. that's it. that's the whole job. let's go ✨

---

🌸 NAME 🌸

rc_avpair_next — iterates through the attribute-value pairs

(no cap, the original description line here was literally just blank, so we're keeping the vibe honest 🙈)

---

🎀 SYNOPSIS 🎀

#include <radcli/radcli.h>

VALUE_PAIR * rc_avpair_next(
    VALUE_PAIR  *t
);

---

✨ DESCRIPTION ✨

so basically, it iterates through the attribute-value pairs. that's the tea 🍵

the attribute-values are organized in a linked-list</>, and this function is literally your girl for walking through them — you hand her the first element to start with, and she keeps going from there. one at a time. no skipping. periodt 💅

---

🦋 PARAMETERS 🦋

• t — the current pair. like, where you're at right now. your current main character 🫶

---

👑 STRUCTURES 👑

⚠️ okay bestie, listen — avoid using this structure directly. use the rc_avpair_get_ functions instead. i'm serious. the struct is giving "don't touch, i'm fragile" 💀

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
};

(the pad[32]? unused. iconic of it to just sit there. slay ✨)

---

🌈 RETURN VALUE 🌈

a pointer to the next pair, or NULL when you're finished. and when it hands you NULL? that's the vibe check saying "we're done here, babe" 💖
