EC_CONFIG_I64(3)

💖 EC_CONFIG_I64 — bestie edition 💖

okay so this is ec_config_i64 from the Libecoli Programmer's Manual (yes the whole page is literally called EC_CONFIG_I64(3), we love a title that eats) ✨

---

🌸 NAME 🌸

ec_config_i64 — create a signed integer configuration value. that's it, that's the whole job, and she does it flawlessly 💅

---

🎀 SYNOPSIS 🎀

#include <ecoli/config.h>

struct ec_config * ec_config_i64(
    int64_t  i64   /* The signed integer value to be set. */
);

so you pull in ecoli/config.h, then you call ec_config_i64 and hand it one (1) int64_t — that's your signed integer, the value you want set. and she hands you back a struct ec_config *. iconic behavior fr fr 🦋

---

👑 RETURN VALUE 👑

you get the configuration object back — the whole point, the main character, the moment 🌟

or… NULL on error 😭 and when that happens, errno is set, so go check it. no guessing bestie, read your errno 💀

not me warning you: NULL means it did NOT work. errno is the receipt 🧾
