PWRITE(3POSIX)

💖 PWRITE — ok bestie, let's write on a file 💖

so this is pwrite(3POSIX), straight out of the POSIX Programmer's Manual ✨ (that's the 3POSIX section, iykyk). Grab a snack, we're doing a whole page 🍓

🌸 PROLOG 🌸

okay so before literally anything else, the important tea:</purgle>

This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. 😭

fr fr bestie, don't come for me if Linux does its own little thing — check the Linux page too 💅

✨ NAME ✨

pwrite — write on a file 📝

that's it. that's the whole name section. short and iconic.

🎀 SYNOPSIS 🎀

#include <unistd.h>

ssize_t pwrite(int fildes, const void *buf, size_t nbyte,
    off_t offset);

look at that signature. four little args. she's cute, she's precise, she does NOT move your file offset 👑

🦋 DESCRIPTION 🦋

Refer to write(). 🫶

yes bestie, that's genuinely the entire description. the manpage said "go read write()" and honestly? valid. slay. periodt. 💅
