💖 STRTOLD(3P) — POSIX Programmer's Manual 💖

okay bestie, so this is the POSIX Programmer's Manual page for strtold, and before we even get into it, there's a lil heads-up you need:

🫶 PROLOG 🫶

This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

ngl that's the whole vibe check right there — POSIX says one thing, your actual Linux box might say another, and sometimes the thing isn't even implemented. always check the Linux page too, fr fr. 💅

✨ NAME ✨

strtold — convert a string to a double-precision number

like. it takes a string. it gives you back a number. the double-precision kind. iconic behavior honestly.

🌸 SYNOPSIS 🌸

#include <stdlib.h>

long double strtold(const char *restrict nptr, char **restrict endptr);

look at that signature, it's giving restrict twice, it's giving long double energy, it's giving "I know exactly what I'm doing". 👑

🦋 DESCRIPTION 🦋

Refer to strtod().

yes. that's it. that's the whole description. the way this page just points you at its sibling and dips? main character energy. 😭 go read strtod() bestie, all the actual deets live over there. iykyk.
