UPSCLI_STRERROR(3)

✨ UPSCLI_STRERROR ✨

ok so this is a page from the NUT Manual — that's Network UPS Tools, bestie — and it's all about one lil function called upscli_strerror. manual section 3, which means it's a library call. iykyk 💅

---

🎀 NAME 🎀

upscli_strerror — returns a string that describes whatever error condition just happened. it's giving "tell me what went wrong" energy 🔥

---

🦋 SYNOPSIS 🦋

#include <upsclient.h>

const char *upscli_strerror(UPSCONN_t *ups);

---

💖 DESCRIPTION 💖

okay so here's the vibe: upscli_strerror() takes that pointer ups, which points at a UPSCONN_t state structure (the thing holding all the deets about your connection), and it hands you back a string describing the last error that went down on this connection. 🫶

one thing tho, bestie, and this is important — the string is only valid until the next call to upscli_strerror(). so if you need it later, copy it. don't be out here holding onto a pointer that's about to change on you 😭 that's a setup for a bad time fr fr.

---

🌸 RETURN VALUE 🌸

it returns a description of the error. and if the error code is something it doesn't recognize? you get an "unknown error" message instead. still helpful, just lowkey mysterious 💀
