💖 ASN1_ITEM_LOOKUP(3ossl) 💖 — bestie, let’s look up some ASN.1 structures ✨

okay so this is the OpenSSL manual page for ASN1_ITEM_lookup and ASN1_ITEM_get — the little lookup girlies for ASN.1 structures. iykyk 🧚

🌸 NAME 🌸

ASN1_ITEM_lookup, ASN1_ITEM_get — lookup ASN.1 structures

🎀 SYNOPSIS 🎀

#include <openssl/asn1.h>

const ASN1_ITEM *ASN1_ITEM_lookup(const char *name);
const ASN1_ITEM *ASN1_ITEM_get(size_t i);

✨ DESCRIPTION ✨

• ASN1_ITEM_lookup() — returns the ASN1_ITEM named name. You give it a name, it gives you the matching struct. no cap 💖
• ASN1_ITEM_get() — returns the ASN1_ITEM with index i. That’s the whole vibe. But bestie, listen: this function returns NULL if the index i is out of range. 🫶

💜 RETURN VALUES 💜

Both ASN1_ITEM_lookup() and ASN1_ITEM_get() return a valid ASN1_ITEM structure, or NULL if an error occurred. That’s the glow-up: valid struct = slay, NULL = check your error situation. 💅
