MODBUS_MAPPING_FREE(3)

💖 MODBUS_MAPPING_FREE — bestie, it's cleanup time 🧹✨

okay so this is a page from the libmodbus Manual and it's literally just about freeing your mapping struct when you're done with it. short king of a manpage but we're gonna give it the full main-character treatment anyway 🫶

---

🌸 NAME 🌸

modbus_mapping_free — free a modbus_mapping_t structure 💅

---

✨ SYNOPSIS ✨

void modbus_mapping_free(modbus_mapping_t *mb_mapping);

like... that's it. that's the whole vibe check. one function, zero drama 🌈

---

🦋 DESCRIPTION 🦋

okay bestie listen up, this one's important. the function shall free the four arrays of the mb_mapping_t structure, and then — and this is the part where it goes full main character — it finally frees the mb_mapping_t referenced by mb_mapping itself 🔥

so it's giving "clean up everything, leave no crumbs." the arrays go first, the struct goes last. no leaks, no mess, no notes. periodt 💅

not me being emotionally attached to a deallocator but here we are 😭

🎀 RETURN VALUE 🎀

There is no return values. none. nada. she returns void and she's thriving, we don't ask questions 💖
