io_finishandshutdown(3)

💖 io_finishandshutdown 💖

okay bestie, gather round, we're talking about io_finishandshutdown from the Library Functions Manual — yes she's a real one, section 3 and everything ✨

🌸 NAME 🌸

io_finishandshutdown — deallocate internal data structures 🧹✨

like. that's it. that's the whole job. she cleans up after the party 🎀

🦋 SYNTAX 🦋

first things first, you gotta bring the header along, no cap:

#include <libowfat/io.h>

and then the function herself, iconic, zero arguments, zero drama:

void io_finishandshutdown();

💅 DESCRIPTION 💅

so io_finishandshutdown deallocates the internal data structures of io_wait(). periodt. she takes all the stuff io_wait() was holding onto and lets it go 🫶

but like — lowkey read the room — this only makes sense if you run your program in a malloc checker and you wanna eliminate the false alarms 💀 because a malloc checker will be like "bestie you leaked!!" and you're like "no babes, that's on purpose" and the checker is like "🚨🚨🚨". so you call this, the checker vibes, everybody's happy 🌈

and here's the thing: your OS will free data structures automatically on process termination. fr fr. the operating system is the ultimate main character who handles cleanup when you exit. so if you're not sitting in a malloc checker, you genuinely do not need to call this. she's not doing anything your OS isn't already gonna do 💖

not a "you must call this" situation, bestie — it's a "you may call this if the malloc checker is being loud" situation. know the difference 👑
