💖 explain_strtof_or_die(3) 💖

okay bestie, welcome to explain_strtof_or_die, a little page from the Library Functions Manual and honestly? she's a whole vibe. 🎀

✨ NAME ✨

explain_strtof_or_die — convert string to number and report errors 💅

---

🌸 SYNOPSIS 🌸

#include <libexplain/strtof.h>
float explain_strtof_or_die(const char *nptr, char **endptr);
float explain_strtof_on_error(const char *nptr, char **endptr))

(yes the second one has two closing parens. no we are not fixing her. she's iconic like that. ✨)

🦋 DESCRIPTION 🦋

so, the explain_strtof_or_die function? her whole job is to call the strtof(3) system call. and if it fails, an explanation gets printed to stderr — that explanation comes from the explain_strtof(3) function — and then the process terminates by calling exit(EXIT_FAILURE). like, she said bye and she meant it. 💀

then there's explain_strtof_on_error, who also calls the strtof(3) system call. on failure she prints an explanation to stderr, also obtained from explain_strtof(3), but she's softer — she still returns to the caller. no dramatic exit. just vibes. 🫶

• nptr — the nptr, exactly as to be passed to the strtof(3) system call. no tweaking, no nothing, pass it through fr fr.
• endptr — the endptr, exactly as to be passed to the strtof(3) system call. same deal, hand her over as-is. 💖

💅 RETURN VALUE 💅

explain_strtof_or_die only returns on success — for the deets on that, go see strtof(3). on failure? she prints an explanation and exits. she does not return. not even a little. 😭

explain_strtof_on_error always returns the value return by the wrapped strtof(3) system call. every time. that's her thing. ⭐

---

🌈 EXAMPLE 🌈

the explain_strtof_or_die function is intended to be used in a fashion similar to the following example:

float result = explain_strtof_or_die(nptr, endptr);

look at her go. main character energy fr. 🔥
