string.h(3avr)

✨ string.h ✨

okay bestie, welcome to the string.h page from the AVR-LibC manual (that's the 3avr section, iykyk) 💖 this is the group chat where all the string-and-memory girlies live. pull up a chair, we're going through every single one of them, no skipping, no scrolling past the "boring" ones. periodt. 💅

🌸 NAME 🌸

string.h — that's it, that's the name, she's an icon and she knows it 🎀

✨ SYNOPSIS ✨

🦋 Macros

• #define _FFS(x) — a macro bestie, just vibing up here at the top of the file 💜

🧚 Functions

lowkey the whole squad is here, so let's do a roll call, one by one, signatures verbatim because we do not mess with the source fr fr:

• int ffs (int __val) — the ffs girlie, taking an int __val 💫
• int ffsl (long __val) — same energy but she's long coded, ffsl with long __val 🌈
• int ffsll (long long __val) — the long long edition, ffsll, very extra, we love her 💅
• void * memccpy (void *, const void *, int, size_t) — memccpy, four args deep, iconic ✨
• void * memchr (const void *, int, size_t) — memchr, out here searching with const void *, int, size_t 🔍
• int memcmp (const void *, const void *, size_t) — memcmp, the compare girlie, two const void * and a size_t 👑
• void * memcpy (void *, const void *, size_t) — memcpy, certified classic, void *, const void *, size_t 💖
• void * memmem (const void *, size_t, const void *, size_t) — memmem, twice the size_t, twice the drama 🍓
• void * memmove (void *, const void *, size_t) — memmove, she moves, that's the whole vibe 🦋
• void * memrchr (const void *, int, size_t) — memrchr, the reverse-coded cousin, no cap ⭐
• void * memset (void *, int, size_t) — memset, setting the tone literally, void *, int, size_t 🎀
• char * strcat (char *, const char *) — strcat, cat girlie, two args, zero notes 💜
• char * strchr (const char *, int) — strchr, out here hunting with const char * and an int 🙈
• char * strchrnul (const char *, int) — strchrnul, the nul twist, very mysterious, very main character 🌸
• int strcmp (const char *, const char *) — strcmp, dueling const char *s, and she returns an int 💫
• char * strcpy (char *, const char *) — strcpy, copy queen, char * into const char * ✨
• int strcasecmp (const char *, const char *) — strcasecmp, the case-insensitive compare bestie, returns int 🔥
• char * strcasestr (const char *, const char *) — strcasestr, searching but make it caseless, obsessed 🌈
• size_t strcspn (const char *__s, const char *__reject) — strcspn, with her named besties __s and __reject, returns size_t 🫶
• char * strdup (const char *s1) — strdup, the duplicator, taking const char *s1 💖
• char * strndup (const char *s, size_t n) — strndup, dupe but with a size_t n limit, we love a boundaried queen 💅
• size_t strlcat (char *, const char *, size_t) — strlcat, the l stands for "we're being responsible", returns size_t 🎀
• size_t strlcpy (char *, const char *, size_t) — strlcpy, same responsible energy, size_t out the door ⭐
• size_t strlen (const char *) — strlen, THE legend, the icon, the moment, returns size_t 👑
• char * strlwr (char *) — strlwr, lowercase era, char * only 🌸
• char * strncat (char *, const char *, size_t) — strncat, strcat's boundaried sister, size_t in the mix 🦋
• int strncmp (const char *, const char *, size_t) — strncmp, compare but limited, returns int 💜
• char * strncpy (char *, const char *, size_t) — strncpy, copy with a size_t cap, so chic ✨
• int strncasecmp (const char *, const char *, size_t) — strncasecmp, caseless AND bounded, a whole overachiever 🔥
• size_t strnlen (const char *, size_t) — strnlen, strlen but she has limits (healthy!), returns size_t 🫶
• char * strpbrk (const char *__s, const char *__accept) — strpbrk, named args __s and __accept, very official 🌈
• char * strrchr (const char *, int) — strrchr, the r girlie, going the other direction 💖
• char * strrev (char *) — strrev, reversing the whole situation, char * 💅
• char * strsep (char **, const char *) — strsep, note the char ** bestie, she's pointer-to-pointer coded 🎀
• size_t strspn (const char *__s, const char *__accept) — strspn, __s and __accept, returns size_t ⭐
• char * strstr (const char *, const char *) — strstr, the search icon, two const char *s, no notes 👑
• char * strtok (char *, const char *) — strtok, the tokenizer, iconic and chaotic 🌸
• char * strtok_r (char *, const char *, char **) — strtok_r, the reentrant version, she has a char ** and she's proud 🦋
• char * strupr (char *) — strupr, uppercase era to close us out, char * only 💜

🎀 Author 🎀

this page was generated automatically by Doxygen for AVR-LibC from the source code — so nobody hand-wrote this, it just manifested, and honestly? that's giving main character energy 🌈✨

---

okay bestie that's the whole page 💖 every macro, every function, every signature, all present and accounted for. nothing skipped, nothing invented, we simply slayed the documentation. 🫶

and that's a wrap, love u, bye!! this was AVR-LibC, Version 2.2.1 — she's the source, she's the version, she's the moment, and she said periodt 💅🎀🌟
