iarray_init(3)

💖 iarray_init(3) — Library Functions Manual 💖

okay bestie, gather round, because we're talking about iarray_init(3) from the Library Functions Manual, section 3, and it's genuinely one of the most chill functions you will ever meet. no drama, no allocation, no failure modes. it's giving ✨low-maintenance icon✨.

🌸 NAME 🌸

iarray_init — initialize iarray data structure

like. that's it. that's the whole job. she initializes the iarray data structure and then she goes home. 🎀

---

🦋 SYNTAX 🦋

first things first, you gotta pull in the header, no cap:

#include <libowfat/iarray.h>

and here's the signature, character for character, don't come for me:

void iarray_init(array* x, size_t elemsize);

and here's the little snippet the page shows, copied exactly:

iarray x;
int64 pos;
t* p = iarray_init(&x,sizeof(element));

that's literally it. pos is just vibing there in the example, minding its own business. 🫶

🌈 DESCRIPTION 🌈

so what does iarray_init actually do? she initializes an iarray so that it can hold elements of size elemsize. that's the whole assignment. 🎯

and here's the part that makes her main character energy: iarray_init does not actually allocate anything. not one single byte. so it literally cannot fail. no error codes, no NULL checks, no 3am panic. it's just a setup step, and it's unbothered, and honestly? we should all be more like her. 💅

no allocation = no failure. that's the deal, and it's a good deal. 🔥

👑 SEE ALSO 👑

go read her friends, they're all iconic:

• iarray_allocate(3)
• iarray_get(3)
• iarray_free(3)

iykyk. the whole iarray friend group is slaying in section 3. 🧚

and that's the page, bestie!! 🦋 this was iarray_init(3) from the Library Functions Manual, and the footer just says iarray_init(3) again because the page is nothing if not consistent. mwah, go forth and initialize something. 💜🌸
