WCSTOIMAX(3POSIX)

💖 WCSTOIMAX(3POSIX) 💖

okay bestie, so this is a page from the POSIX Programmer's Manual — the POSIX girlies' own manual, not the Linux one, iykyk.

PROLOG heads-up: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (so like, go check the corresponding Linux manual page for the tea on Linux behavior), or the interface might not even be implemented on Linux at all. 🙈

✨ NAME ✨

wcstoimax, wcstoumax — convert a wide-character string to an integer type 💅

---

🌸 SYNOPSIS 🌸

#include <stddef.h>
#include <inttypes.h>

intmax_t wcstoimax(const wchar_t *restrict nptr,
    wchar_t **restrict endptr, int base);
uintmax_t wcstoumax(const wchar_t *restrict nptr,
    wchar_t **restrict endptr, int base);

---

🦋 DESCRIPTION 🦋

So the functionality described on this reference page is aligned with the ISO C standard. If there's any conflict between the requirements described here and the ISO C standard, that conflict is unintentional — no drama intended, fr fr. This volume of POSIX.1‐2017 defers to the ISO C standard. periodt.

These functions shall be equivalent to the wcstol(), wcstoll(), wcstoul(), and wcstoull() functions, respectively — except that the initial portion of the wide string shall be converted to intmax_t and uintmax_t representation, respectively. it's giving "same energy, bigger integer" 😌

---

💜 RETURN VALUE 💜

These functions shall return the converted value, if any.

If no conversion could be performed, zero shall be returned. If the correct value is outside the range of representable values, {INTMAX_MAX}, {INTMAX_MIN}, or {UINTMAX_MAX} shall be returned (according to the return type and sign of the value, if any), and errno shall be set to [ERANGE]. bestie that's the overflow moment 😭

---

🎀 ERRORS 🎀

These functions shall fail if:

• EINVAL — the value of base is not supported. nope, not that base. 💀
• ERANGE — the value to be returned is not representable. too big, too small, we simply cannot 🫶

These functions may fail if:

• EINVAL — no conversion could be performed.

The following sections are informative. 👑

None. yeah. nothing. we're keeping it mysterious ✨

🌈 APPLICATION USAGE 🌈

None. iconic behavior honestly 💅

🧚 RATIONALE 🧚

None. no thoughts, just vibes 🌸

---

🔥 FUTURE DIRECTIONS 🔥

None. the future is wide open, literally (wide-character, get it) 💖

and that's the whole page bestie!! this one came from IEEE/The Open Group, 2017, filed under WCSTOIMAX(3POSIX) — slay, stay hydrated, and always check your errno 💅✨
