TWALK(3POSIX)

🦋 PROLOG 🦋

okay bestie, real talk before we even get into it: this manual page is part of the POSIX Programmer's Manual. that's the whole vibe. but here's the tea — the Linux implementation of this interface may differ, so if you're on Linux you should go consult the corresponding Linux manual page for the actual deets. and sometimes? the interface just isn't implemented on Linux at all. rude, but true. 💀

🌸 NAME 🌸

twalk — traverse a binary search tree

like, you walk the tree. twalk. it's giving on the nose, and honestly? we love a self-explanatory name. 👑

✨ SYNOPSIS ✨

#include <search.h>

void twalk(const void *root,
    void (*action)(const void *, VISIT, int ));

that's it. that's the whole signature. no return value, no drama. 🫶

💖 DESCRIPTION 💖

okay so. the actual description? refer to tdelete(). that's it, that's the whole thing. the POSIX girlies really said "go read the other page bestie, it's all there." iconic minimalism, no notes. 💅
