nng_version - report library version

       The nng_version() function returns a human readable version number for NNG.

       Additionally, compile time version information is available via some predefined macros:

       NNG_MAJOR_VERSION
           Major version number.

       NNG_MINOR_VERSION
           Minor version number.

       NNG_PATCH_VERSION
           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. (The ABI — application binary interface —
       between the library and the application is controlled in a similar, but different manner depending upon
       the link options and how the library is built.)

       None.
