asn1_encode_integer(9)

🌸 asn1_encode_integer(9) 🌸

okay so bestie, welcome to the Kernel API Manual 💅 today’s main character is asn1_encode_integer(9), and she is here to help you encode a positive integer to ASN.1. no cap, it’s giving tiny-but-iconic encoder energy 🎀

💖 NAME 💖

asn1_encode_integer — encode positive integer to ASN.1 ✨

🎀 SYNOPSIS 🎀

unsigned char * asn1_encode_integer (unsigned char *data , const
       unsigned char *end_data , s64 integer );

yep, that’s the whole signature, bestie — keep it exactly like that 🫶

🦋 ARGUMENTS 🦋

• data — pointer to the pointer to the data 👀 yes, literally a pointer to the pointer, she said what she said.
• end_data — end of data pointer, points one beyond last usable byte in data 🚧
• integer — integer to be encoded 🧮

🌈 DESCRIPTION 🌈

okay so real talk: this is a simplified encoder. it only currently does positive integers, but it should be simple enough to add the negative case if a use comes along. so if your integer is positive, slay; if it’s negative, that’s a future-episode plotline 👑💖
