💖 PROLOG 💖

okay bestie, real talk before we even start — 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), or honestly the interface might not even be implemented on Linux at all. 🙈 not me warning you twice but here we are.

✨ NAME ✨

clearerr — clear indicators on a stream 🧼

🌸 SYNOPSIS 🌸

#include <stdio.h>

void clearerr(FILE *stream);

💅 DESCRIPTION 💅

So the functionality on this reference page is aligned with the ISO C standard. If anything here conflicts with the requirements described in the ISO C standard, that conflict is unintentional — no cap. 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 to which stream points. like, it's the lil reset button for your stream's mood 🫶

And super importantly: the clearerr() function shall not change the setting of errno if stream is valid. iykyk — that's the whole point.

⭐ RETURN VALUE ⭐

The clearerr() function shall not return a value. it's giving void, it's giving nothing to see here, and honestly? iconic. 👑
