🦋 strings.h(7POSIX) — POSIX Programmer's Manual 🦋

okay bestie, sit down, hydrate, because we're doing the <strings.h> deep dive and it's literally so cute. this is page strings.h(7POSIX) from the POSIX Programmer's Manual, and yes, she's serving. 💅

✨ PROLOG ✨

okay so real talk first, no cap: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so if you're on Linux, go consult the corresponding Linux manual page for the deets on Linux behavior. Or, plot twist, the interface might not even be implemented on Linux at all. 🙈 Check before you ship, bestie.

💖 NAME 💖

strings.h — string operations. that's it, that's the vibe. 🎀

🌸 SYNOPSIS 🌸

#include <strings.h>

🌈 DESCRIPTION 🌈

so here's the tea: the following shall be declared as functions and may also be defined as macros. Function prototypes shall be provided for use with ISO C standard compilers. periodt.

int    ffs(int);
int    strcasecmp(const char *, const char *);
int    strcasecmp_l(const char *, const char *, locale_t);
int    strncasecmp(const char *, const char *, size_t);
int    strncasecmp_l(const char *, const char *, size_t, locale_t);

look at her go ✨ five whole function signatures, all iconic.

The <strings.h> header shall define the locale_t type as described in <locale.h>. 🫶

The <strings.h> header shall define the size_t type as described in <sys/types.h>. 🫶

The following sections are informative. (iykyk — that means they're not the normative requirements, they're just the commentary track. 💀)

😭 APPLICATION USAGE 😭

None.

like. none. nothing. empty. the void. 🕳️ she said "no notes."

💜 RATIONALE 💜

None.

again — none. truly nothing to explain. she's self-evident and she knows it. 👑

🧚 FUTURE DIRECTIONS 🧚

None.

no glow-up planned. she's perfect as is. ⭐

okay bestie, legal moment, stay with me, it's giving very serious but we gotta keep every word. 🫡

and that's the whole page, bestie. 🎀 this absolute baddie of a header page is brought to you by IEEE/The Open Group, 2017, and she answers to strings.h(7POSIX). mwah. 💖✨🦋
