asn1_expand_any_defined_by(3)

💖 NAME 💖

asn1_expand_any_defined_by — bestie, this is an API function, and it's about to expand your ANYs, no cap ✨

---

🦋 SYNOPSIS 🦋

#include <libtasn1.h>

int asn1_expand_any_defined_by(asn1_node_const definitions, asn1_node *
element);

---

🌸 ARGUMENTS 🌸

• asn1_node_const definitions — the ASN1 definitions, like the blueprint of the whole vibe 🎀
• asn1_node * element — a pointer to an ASN1 structure, aka the thing we're about to glow up 💅

---

✨ DESCRIPTION ✨

Okay so picture this: you've got a structure that came out of a DER decoding process (that's the asn1_der_decoding function, iykyk), and inside it there are "ANY DEFINED BY" elements just sitting there like unopened presents. This function expands every single one of them. Not some. Every. 👑

The catch? The element ANY must be defined by an OBJECT IDENTIFIER — that's the rule, periodt.

And the type it uses to expand that element ANY is the first one following the definition of the actual value of the OBJECT IDENTIFIER. So it's not guessing, it's reading the room and picking the next thing in line. Slay. 🔥

---

🌈 RETURNS 🌈

• ASN1_SUCCESS — substitution OK, we ate, no crumbs 💖
• ASN1_ERROR_TYPE_ANY — some "ANY DEFINED BY" element could not be expanded because there was a problem in the OBJECT ID -> TYPE association 😭 like the link-up just didn't happen
• other error codes — depending on DER decoding, because sometimes the DER decoding itself is the one acting up 💀
