EC_STR_PARSE_ULLINT(3)

✨ EC_STR_PARSE_ULLINT ✨

okay so bestie, welcome to the Libecoli Programmer's Manual 💖 this one's about ec_str_parse_ullint — she parses a string into an unsigned integer, and she does it flawlessly. no cap. 🎀

---

🌸 NAME 🌸

ec_str_parse_ullint — parse a string for an unsigned integer 💅

---

🦋 SYNOPSIS 🦋

#include <ecoli/string.h>

int ec_str_parse_ullint(
    const char   *str,   /* The string to parse. */
    unsigned int  base,  /* The base (0 means "guess"). */
    uint64_t      min,   /* The minimum allowed value. */
    uint64_t      max,   /* The maximum allowed value. */
    uint64_t     *val    /* The pointer to the value to be set on success. */
);

like, look at her. five args, all business 👑

• str — the string you want parsed, bestie.
• base — the base. and listen, 0 means "guess" 👀 she'll figure it out herself, main character energy.
• min — the minimum allowed value.
• max — the maximum allowed value.
• val — pointer to the value that gets set on success. on success only, ok? don't come for her otherwise 🙈

---

🌈 RETURN VALUE 🌈

on success? she returns 0. iconic. ✨

otherwise she returns -1 and sets errno — so go check errno, she left you a note 💌

ngl if you're ignoring errno after a -1 that's a you problem, not a her problem 😭
