BSON_ALIGNED_ALLOC0(3)

💅 BSON_ALIGNED_ALLOC0 💅

okay bestie, so this one is from libbson and it's literally the page for BSON_ALIGNED_ALLOC0(3) — say that three times fast, i dare you 🫶

---

✨ SYNOPSIS ✨

void *
bson_aligned_alloc0 (size_t alignment, size_t num_bytes);

that's it, that's the whole vibe check 🌸

---

🎀 PARAMETERS 🎀

• alignment — the alignment of the allocated bytes of memory. and no, you can't just put whatever here: it must be a power of 2 and a multiple of sizeof (void *). both. at the same time. iykyk 💅
• num_bytes — the number of bytes to allocate. this one must be a multiple of alignment. like they have to be in a situationship that actually works mathematically 🔥

---

🦋 DESCRIPTION 🦋

so this is a portable aligned_alloc() wrapper — and plot twist, it also sets the memory to zero. iconic behaviour, honestly 👑

and ngl, if there was a failure to allocate num_bytes bytes aligned to alignment, the process will be aborted. not "returns an error". not "returns NULL". it aborts. the whole thing. done. 💀

⚠️ WARNING: this function will abort on failure to allocate memory. like, that is the entire error-handling strategy. no cap. proceed accordingly bestie 😭

---

🌈 RETURNS 🌈

a pointer to a memory region which HAS been zeroed. capital H-A-S, they really wanted you to know. every byte, squeaky clean, zeroed out, main character energy ⭐
