πŸ’– asn1_dup_node(3) β€” the libtasn1 one, section 3 πŸ’–

okay bestie, gather round, because today we're talking about asn1_dup_node from libtasn1. yes it's a C API function, yes it's in section 3 of the manual, and yes it's lowkey iconic. let's get into it πŸ¦‹


✨ NAME ✨

asn1_dup_node β€” it's an API function, babes. that's the whole vibe. πŸ’…


🌸 SYNOPSIS 🌸

first things first, you gotta pull in the header, no cap:

#include <libtasn1.h>

and then, the moment you've all been waiting for, the signature itself:

asn1_node asn1_dup_node(asn1_node_const src, const char * src_name);

look at her. main character energy fr fr. πŸ‘‘


πŸŽ€ ARGUMENTS πŸŽ€

  • asn1_node_const src β€” this is your source asn1 node. the original. the blueprint. the one we're copying from, bestie. she stays untouched, that's the whole point of the const. 🫢
  • const char * src_name β€” this is the field name in the source node. yes, the field name inside src. that's the one. πŸ“

πŸ’« DESCRIPTION πŸ’«

okay so here's the tea β˜• β€” this function creates a deep copy of an asn1_node variable. not a shallow little surface-level situationship copy, a deep one. she goes all the way down.

and the way that it returns an exact copy of the provided structure? obsessed. literally an identical twin. same structure, same everything, but a whole separate being. πŸ’–βœ¨


⭐ RETURNS ⭐

and if things go wrong? she returns NULL on failure. that's it, that's the signal. no drama, just NULL. so like, always check, bestie, always check. πŸ™ˆ
