✨ explain_readdir_or_die β€” the manual page, but make it make sense πŸ’…

okay bestie, welcome to explain_readdir_or_die(3) β€” a Library Functions Manual moment. It's giving "read one directory entry, but with feelings and also consequences." Let's go πŸ¦‹


πŸŽ€ NAME πŸŽ€

explain_readdir_or_die β€” read a directory entry and report errors, loudly, and then dip.


🌸 SYNOPSIS 🌸

#include <libexplain/readdir.h>
struct dirent *explain_readdir_or_die(DIR *dir);

like. that's the whole vibe. one function, one DIR *, one struct dirent * coming back at you. iconic honestly.


πŸ’– DESCRIPTION πŸ’–

so here's the tea: explain_readdir_or_die is the function you call when you want to call the readdir(2) system call. that's it. that's the job.

but β€” and this is the main character part β€” if it fails, an explanation gets printed to stderr. where does that explanation come from? from explain_readdir(3), obviously. and then, bestie, the process terminates by calling exit(EXIT_FAILURE). no takebacks. no second chances. periodt.

this function is intended to be used in a fashion similar to the following example:

explain_readdir_or_die(dir);

that's literally it. that's the whole example. slay.

  • dir β€” the dir, exactly as to be passed to the readdir(2) system call. like, don't get creative with it. same dir, same energy.

Returns:

  • a pointer to a dirent structure, or NULL if end-of-file is reached. and if it fails? it prints an explanation and exits. that's the deal. 🫢
