💖 PUTCHAR(3POSIX) — the POSIX Programmer's Manual, bestie edition 💖

okay so welcome to the POSIX Programmer's Manual page for putchar, and it's giving "tiny function, big main character energy". ✨

🌸 PROLOG 🌸

ngl, this manual page is part of the POSIX Programmer's Manual. But heads up, bestie — the Linux implementation of this interface may differ (so pls consult the corresponding Linux manual page for the deets on Linux behavior), or honestly the interface may not be implemented on Linux at all. 💀 Not every platform shows up to the party.

✨ NAME ✨

putchar — put a byte on a stdout stream 🫶

🎀 SYNOPSIS 🎀

#include <stdio.h>

int putchar(int c);

💅 DESCRIPTION 💅

So the functionality described on this reference page is aligned with the ISO C standard. And like, if there's any conflict between the requirements described here and the ISO C standard, that conflict is unintentional — nobody's trying to start drama. This volume of POSIX.1‐2017 defers to the ISO C standard, periodt.

The function call putchar(c) shall be equivalent to putc(c,stdout). That's it. That's the whole vibe. 👑

🔥 RETURN VALUE 🔥

Refer to fputc(). (Yeah, it's a "go ask her" situation. iykyk.)

🌈 ERRORS 🌈

Refer to fputc(). Same energy, same friend. 💜

The following sections are informative — so like, bonus content, not the main plot.

🦋 APPLICATION USAGE 🦋

⭐ RATIONALE ⭐

None. 🧚

💜 FUTURE DIRECTIONS 💜

None. 🌸
