💖 nbdkit_parse_bool(3) 💖

okay bestie, so this one lives in the nbdkit manual, section 3, and it's literally the cutest little helper for turning human words into 0s and 1s. no cap.

✨ NAME ✨

nbdkit_parse_bool — parse human-readable boolean strings for nbdkit

---

🌸 SYNOPSIS 🌸

#include <nbdkit-plugin.h>

int nbdkit_parse_bool (const char *str);

---

🦋 DESCRIPTION 🦋

so you got a string, right? and it's like "on" or "off" or "true" or "no" or whatever, and you need it to be an actual boolean. that's it, that's the function. 💅

Use the nbdkit_parse_bool utility function to parse human-readable strings such as "on", "off", "true", "no" etc into a boolean value. she's simple, she's iconic, she slays. 👑

---

⭐ RETURN VALUE ⭐

• The function returns 0 or 1 if the parse was successful. ✨
• If there is an error it calls nbdkit_error(3) and returns -1. 😭 (yes, error handling, we love a girl who reports her problems)

---

🎀 LANGUAGE BINDINGS 🎀
