💅 sysdecode_cap_rights(3) — bestie edition

okay so bestie, gather round, because we're talking about sysdecode_cap_rights from the Library Functions Manual, living in the libsysdecode library, and honestly? it's giving "tiny function, big brain energy" 💖

---

✨ NAME ✨

sysdecode_cap_rights — outputs a list of capability rights, periodt 💅

---

🎀 LIBRARY 🎀

library “libsysdecode” — that's the one, bestie, that's where she lives 🦋

---

🌸 SYNOPSIS 🌸

#include <sysdecode.h>

void
sysdecode_cap_rights(FILE *fp, cap_rights_t *rightsp);

---

🧚 DESCRIPTION 🧚

okay so here's the vibe: sysdecode_cap_rights() outputs a comma-separated list of capability rights at rightsp to the stream fp. literally just writes them out, comma-separated, into your stream, no cap 🔥

now this is the part where you gotta pay attention, bestie, because it's lowkey the whole personality of this function 👀 — some capability rights are supersets of others. for example, CAP_PREAD is the union of CAP_READ and CAP_SEEK. iconic of her, honestly.

so what does sysdecode_cap_rights() do about that? she emits a minimal list of rights whose union is equal to *rightsp. the way that she's out here being efficient with her words 💅

fr fr, here's the example: if both CAP_READ and CAP_SEEK are set in *rightsp, then sysdecode_cap_rights() will include only CAP_PREAD in the output list. like, she said "i know what you meant" and just said it once. main character energy 👑
