NNG_FREE(3)

✨ NAME ✨

nng_free — free memory 💖

okay so this is the NNG_FREE(3) page from the NNG Reference Manual, and it is literally all about giving memory back. no cap.

---

🛠️ SYNOPSIS 🛠️

#include <nng/nng.h>

void nng_free(void *ptr, size_t size);

---

🌸 DESCRIPTION 🌸

The nng_free() function deallocates a memory region of size size, that was previously allocated by nng_alloc() or nng_recv() with the NNG_FLAG_ALLOC flag. that's the whole vibe bestie. 🎀

Important — it is very important that size match the allocation size used to allocate the memory. fr fr. do not play games with the size. 😭

Important — do not attempt to use this function to deallocate memory obtained by a call to the system malloc() or calloc() functions, or the C++ new operator. doing so may result in unpredictable behavior, including corruption of application memory. that's not a cute look. that's a 💀 look. do not do it.
