💅 ecryptfs_from_hex(9) — Kernel API Manual

okay bestie, we’re in the Kernel API Manual and this page is ecryptfs_from_hex(9) — short, sweet, and very “here’s the signature, now go off” energy ✨

✨ NAME ✨

• ecryptfs_from_hex — that’s the name, and the original one-liner after the dash is blank, no cap 😭

🌸 SYNOPSIS 🌸

void ecryptfs_from_hex (char *dst , char *src , int dst_size );

It’s void, so there’s no return value to catch, bestie 🫶

🎀 ARGUMENTS 🎀

• dst — buffer to take the bytes from src hex; must be at least of size (src_size / 2)
• src — buffer to be converted from a hex string representation to raw value
• dst_size — size of dst buffer, or number of hex characters pairs to convert
