+# nng_version
+
+## NAME
+
+nng_version --- report library version
+
+## SYNOPSIS
+
+```c
+#include <nng/nng.h>
+
+const char * nng_version(void);
+```
+
+## DESCRIPTION
+
+The `nng_version()` function returns a human readable {{i:version number}}
+for _NNG_.
+
+Additionally, compile time version information is available
+via some predefined macros:
+
+- {{i:`NNG_MAJOR_VERSION`}}: Major version number.
+- {{i:`NNG_MINOR_VERSION`}}: Minor version number.
+- {{i:`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 {{i:ABI}} -- {{i: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.)
+
+## RETURN VALUES
+
+`NUL`-terminated string containing the library version number.
+
+{{#include ../refs.md}}
