CLEARERR(3POSIX)

📦 version 2017a, in debian bookworm, debian trixie, ubuntu jammy, ubuntu noble, ubuntu resolute, ubuntu stonking

✨ PROLOG ✨

okay bestie, real talk before we dive in 💖 this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (so like, go check the corresponding Linux manual page for the deets on Linux behavior, fr), or honestly? the interface might not even be implemented on Linux at all. 💀

🌸 NAME 🌸

clearerr — clear indicators on a stream

🎀 SYNOPSIS 🎀

#include <stdio.h>

void clearerr(FILE *stream);

💅 DESCRIPTION 💅

okay so the functionality on this reference page is aligned with the ISO C standard. If there's any conflict between what's written here and the ISO C standard, that conflict is unintentional — no drama intended. This volume of POSIX.1‐2017 defers to the ISO C standard. periodt. 👑

The clearerr() function shall clear the end-of-file and error indicators for the stream that stream points to. That's it. That's the whole job. iconic behavior honestly. ✨

And here's the cute part: the clearerr() function shall not change the setting of errno if stream is valid. she minds her own business. 🫶

🌈 RETURN VALUE 🌈

The clearerr() function shall not return a value. she gives you nothing back and that's on purpose, no cap. 💅
