rc_avpair_parse(3)

rc_avpair_parse 💖

okay so this is a page from the Radius client library manuals — the radcli girlies know 💅. Pull up a chair bestie, we're parsing attribute-value pairs and it's gonna be iconic ✨

---

NAME 🎀

rc_avpair_parse — yes that's the whole name, she's mysterious like that, the description line was literally empty and we respect the minimalism era 🦋

---

SYNOPSIS ✨

#include <radcli/radcli.h>

int rc_avpair_parse(
    rc_handle const  *rh,
    char const       *buffer,
    VALUE_PAIR      **first_pair
);

three args, one int, no skips 🫶

---

DESCRIPTION 🌸

So basically? It parses the buffer to extract the attribute-value pairs. That's the whole job. She's a parser, she eats text, she hands you pairs. main character energy tbh 👑

---

PARAMETERS 💜

• rh — a handle to parsed configuration. your config bestie, already parsed and ready to go ✨
• buffer — the buffer to be parsed. the raw text going in, she's the snack fr fr 🍓
• first_pair — an allocated array of values. this is where the extracted pairs land, so pls make sure it's allocated before you hand it over 😭

---

STRUCTURES 🦋

okay bestie, real talk: Avoid using this structure directly. Use the rc_avpair_get_ functions. Like, no cap, do NOT touch her. She's got a "look don't touch" vibe and the rc_avpair_get_ crew is who you actually call 💅

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
};

quick field tour because i know you're nosy (same):

• name — the attribute name, but only if it's known 🌸
• attribute — the numeric value, type rc_attr_id, vendor included; split it with VENDOR() and ATTRID() iykyk 🔥
• type — the attribute type 💫
• lvalue — the value when type is PW_TYPE_INTEGER, PW_TYPE_DATE or PW_TYPE_IPADDR 🧚
• strvalue — the value in every other case 💜
• next — the next one in the chain, it's giving linked list 🌈
• pad[32] — unused pad, she's just sitting there, decorative, unemployed 💀

---

RETURN VALUE ⭐

• 0 — successful parse of attribute-value pair, we ate, no crumbs 🎀
• -1 — syntax (or other) error detected, sad girl hours 😭
