ASN1_INTEGER_NEW(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💖 ASN1_INTEGER_NEW(3ossl) 💖

okay so we're in <openssl/asn1.h> territory today bestie, and this one is genuinely a tiny little page about making and unmaking an ASN1_INTEGER. it's from the OpenSSL manual (3ossl), and no cap it's short — but every single detail matters so let's go ✨

🌸 SYNOPSIS 🌸

#include <openssl/asn1.h>

ASN1_INTEGER *ASN1_INTEGER_new(void);
void ASN1_INTEGER_free(ASN1_INTEGER *a);

like, that's it. that's the whole flex. 💅

🦋 DESCRIPTION 🦋

ASN1_INTEGER_new() returns an allocated ASN1_INTEGER structure. it's giving "give me a fresh one, I'll handle the rest" energy 🎀

ASN1_INTEGER_free() frees up a single ASN1_INTEGER object. important little detail: if the argument is NULL, nothing is done — she's unbothered, she simply does not react 😌. so you can pass NULL and nothing bad happens, iykyk.

and for the vibe check: an ASN1_INTEGER structure is the thing that represents the ASN.1 INTEGER type. that's literally its whole main character job 👑

⭐ RETURN VALUES ⭐

  • ASN1_INTEGER_new() returns a valid ASN1_INTEGER structure, or NULL if an error occurred 😭 (yes the typo "return" is in spirit, but the facts are: valid struct, or NULL on error).
  • ASN1_INTEGER_free() does not return a value. she gives nothing back, and that's fine 🫶
ngl bestie, if ASN1_INTEGER_new() hands you NULL, that's your "error occurred" signal — treat it as such and don't go dereferencing it, okay? 💀
