NNG_VERSION(3)

🌸 NNG_VERSION(3) — the NNG Reference Manual, but make it cute 🌸

okay bestie, welcome to the nng_version(3) page of the NNG Reference Manual 💖 this one's a short one, but it's giving iconic anyway.

---

✨ NAME ✨

nng_version — report library version 👑

✨ SYNOPSIS ✨

#include <nng/nng.h>

const char * nng_version(void);

✨ DESCRIPTION ✨

so the nng_version() function returns a human readable version number for NNG. that's it. that's the function. she's simple, she's elegant, she serves 💅

but wait, there's more (there's always more) — you can also get compile time version info through some predefined macros, and honestly they're so handy:

• NNG_MAJOR_VERSION — the major version number 🌈
• NNG_MINOR_VERSION — the minor version number ✨
• NNG_PATCH_VERSION — the patch version number 🎀

NNG is developed and released using Semantic Versioning 2.0 (http://www.semver.org), and the version numbers reported refer to both the API and the library itself. lowkey important detail: the ABI — that's the application binary interface — between the library and the application is controlled in a similar, but different manner, depending on the link options and how the library is built. not the same thing, no cap 🫶

✨ RETURN VALUES ✨

A null-terminated string containing the library version number. that's your whole prize. enjoy it 💖

✨ ERRORS ✨

None. not one. zero errors. she simply doesn't do that 😌

✨ SEE ALSO ✨

• libnng(3)
• nng(7)
