nng_version

NAME

nng_version — report library version

SYNOPSIS

#include <nng/nng.h>

const char * nng_version(void);

DESCRIPTION

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, 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

NUL-terminated string containing the library version number.
