KCAPI_RNG_SEEDSIZE(3)

💖 KCAPI_RNG_SEEDSIZE 💖

okay bestie, welcome to kcapi_rng_seedsize — it's a lil function from the libkcapi programming interface (that's the manual section 3 situation, iykyk) and it is SO simple it's almost criminal. Let's get into it. 🫶

---

✨ SYNOPSIS ✨

uint32_t kcapi_rng_seedsize(struct kcapi_handle * handle);

that's it. that's the whole signature. one argument, one return value, zero drama. 💅

---

🌸 ARGUMENTS 🌸

• handle — [in] the cipher handle. yeah bestie, you gotta hand it your handle. it's an in parameter, meaning it goes in and (per the docs) doesn't come back out all mangled. you just pass the thing. 🎀

---

🦋 DESCRIPTION 🦋

so here's the tea: this function returns the required seed size of the DRNG. that's its whole personality. ✨

what comes back:

• > 0 — slay, this specifies the block size 🔥
• 0 — 😭 error. something went wrong. not the vibe.

no cap, 0 is the sad path here — if you see a zero come back, that's not a seed size, that's a problem. don't go using it like it's a valid number. 🙈

okay so the original page doesn't actually list any SEE ALSO entries — nothing to send you off to. so instead: go forth, call the function, and check for that zero. that's the assignment. periodt. 💖
