This documentation is for version v1.3.0 of NNG, but the latest released version is v1.8.0. see the documentation for v1.8.0 for the most up-to-date information.

SYNOPSIS

#include <nng/nng.h>

const char * nng_version(void);

DESCRIPTION

The nng_version() function returns a human readable version number for the nng library. This is intended for output in programs, and so forth.

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.

The nng library is developed and released using Semantic Versioning 2.0, 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.)

RETURN VALUES

C string (NUL-terminated) containing the library version number.

ERRORS

None.
