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

okay so quick heads up before we even start: this page lives in the POSIX Programmer's Manual. The Linux implementation of this interface may differ — like, go check the matching Linux man page for the actual Linux tea — or honestly the interface might not even be implemented on Linux at all. 🙈

✨ PROLOG ✨

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.

🌸 NAME 🌸

strchr — string scanning operation. that's the whole vibe: we scan a string. 🔍

🎀 SYNOPSIS 🎀

#include <string.h>

char *strchr(const char *s, int c);

🦋 DESCRIPTION 🦋

So the functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional — no drama intended, fr fr. This volume of POSIX.1‐2017 defers to the ISO C standard. 👑

Now the actual main character move: the strchr() function shall locate the first occurrence of c (converted to a char) in the string pointed to by s. And listen — the terminating NUL character is considered to be part of the string. So yes, it counts. Not me including the null terminator in the group chat 💀

💅 RETURN VALUE 💅

Upon completion, strchr() shall return a pointer to the byte, or a null pointer if the byte was not found. found it = pointer, didn't find it = NULL. simple as that, periodt.

💀 ERRORS 💀

No errors are defined.

The following sections are informative.

🍓 EXAMPLES 🍓
