search.h(7POSIX)

🎀 search.h(7POSIX) — the search tables page, bestie edition 🎀

okay so this is search.h from the POSIX Programmer's Manual, and I'm gonna walk you through it like we're texting at 2am. 💖

✨ PROLOG ✨

Real talk first, bestie: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so if you're actually on Linux, consult the corresponding Linux manual page for the details of Linux behavior. Orrr the interface might not be implemented on Linux at all. 🙈 Vibe check your platform, fr fr.

🌸 NAME 🌸

search.h — search tables. that's it, that's the whole name. iconic. 👑

---

🦋 SYNOPSIS 🦋

#include <search.h>

---

💅 DESCRIPTION 💅

The <search.h> header shall define the ENTRY type for structure entry, and that structure shall include the following members:

char    *key
void    *data

And it shall define ACTION and VISIT as enumeration data types through type definitions, like this:

enum { FIND, ENTER } ACTION;
enum { preorder, postorder, endorder, leaf } VISIT;

The <search.h> header shall define the size_t type as described in <sys/types.h>. iykyk. ✨

The following shall be declared as functions and may also be defined as macros. Function prototypes shall be provided. 🫶

int    hcreate(size_t);
void   hdestroy(void);
ENTRY *hsearch(ENTRY, ACTION);
void   insque(void *, void *);
void  *lfind(const void *, const void *, size_t *,
          size_t, int (*)(const void *, const void *));
void  *lsearch(const void *, void *, size_t *,
          size_t, int (*)(const void *, const void *));
void   remque(void *);
void  *tdelete(const void *restrict, void **restrict,
          int(*)(const void *, const void *));
void  *tfind(const void *, void *const *,
          int(*)(const void *, const void *));
void  *tsearch(const void *, void **,
          int(*)(const void *, const void *));
void   twalk(const void *,
          void (*)(const void *, VISIT, int ));

The following sections are informative. 🧚 (yes bestie, that means exactly what it says — they're informative, not normative. noted. 📝)

🍓 APPLICATION USAGE 🍓

None. nothing. zero. the void. 💀

---

🌈 RATIONALE 🌈

None. also nothing. we love a low-effort section, slay. 💅

---

⭐ FUTURE DIRECTIONS ⭐

None. the future is, apparently, more nothing. ✨
