详细描述

VLink library version constants, build-time feature flags, and compile-time comparison helpers.

This header is the single source of truth for the VLink library version triple and for the set of optional subsystems compiled into the build. When the CMake-generated version_config.h is present in the include tree it is preferred; otherwise the fallback #define block below supplies the default values used by header-only or out-of-tree builds.

Version Macros

Macro	Type	Meaning
VLINK_VERSION_MAJOR	integer literal	Major version component.
VLINK_VERSION_MINOR	integer literal	Minor version component.
VLINK_VERSION_PATCH	integer literal	Patch version component.
VLINK_VERSION	string literal	Dot-separated version string, e.g. "2.0.0".
VLINK_VERSION_TIMESTAMP	string literal	Build timestamp (empty in fallback builds).
VLINK_VERSION_TAG	string literal	Git tag (empty in fallback builds).
VLINK_VERSION_COMMIT_ID	string literal	Git commit hash (empty in fallback builds).
VLINK_VERSION_CHECK(a,b,c)	24-bit integer	Packs a version triple for compile-time compare.
VLINK_VERSION_VALUE	24-bit integer	Encoded current version for use with the check.

Feature-flag Macros (selected subset)

Macro	Subsystem
VLINK_ENABLE_CXX_STD_20	Compile-time opt-in to C++20 facilities.
VLINK_ENABLE_C_API	Pure C wrapper API (see external/c_api.h).
VLINK_ENABLE_SECURITY	Built-in security backends and Security* nodes.
VLINK_ENABLE_SQLITE	SQLite-backed bag storage.
VLINK_ENABLE_ZSTD	Zstd compression for bag files (off by default).
VLINK_ENABLE_PROXY	Proxy monitoring API (see external/proxy_api.h).
VLINK_ENABLE_CLI_*	Individual CLI sub-commands (info, bag, monitor...).
VLINK_ENABLE_LOG_*	Optional logging back-ends (NAT, SPD, DLT, QUI).
VLINK_ENABLE_TEST	Unit-test build artefacts.

Compile-time Version Check

#include <vlink/version.h>
 
#if VLINK_VERSION_VALUE >= VLINK_VERSION_CHECK(2, 0, 0)
  // Safe to use APIs introduced in VLink 2.0.0
#endif

Runtime Version Read

#include <vlink/version.h>
#include <iostream>
 
void print_vlink_version() {
  std::cout << "VLink " << VLINK_VERSION << "\n"
            << "  major = " << VLINK_VERSION_MAJOR << "\n"
            << "  minor = " << VLINK_VERSION_MINOR << "\n"
            << "  patch = " << VLINK_VERSION_PATCH << "\n";
}

VLINK_VERSION_CHECK

#define VLINK_VERSION_CHECK	(		major,
			minor,
			patch
	)		(((major) << 16) | ((minor) << 8) | (patch))

Packs a (major, minor, patch) triple into a single 24-bit integer.

Stores major in bits 23-16, minor in bits 15-8, and patch in bits 7-0. Use together with VLINK_VERSION_VALUE to write compile-time version guards.

参数

major	Major component (0-255).
minor	Minor component (0-255).
patch	Patch component (0-255).

返回

Encoded 24-bit integer.

VLINK_VERSION_COMMIT_ID

#define VLINK_VERSION_COMMIT_ID   ""

VLINK_VERSION_MAJOR

#define VLINK_VERSION_MAJOR   2

VLINK_VERSION_MINOR

#define VLINK_VERSION_MINOR   0

VLINK_VERSION_PATCH

#define VLINK_VERSION_PATCH   0

VLINK_VERSION_TAG

#define VLINK_VERSION_TAG   ""

VLINK_VERSION_TIMESTAMP

#define VLINK_VERSION_TIMESTAMP   ""

VLINK_VERSION_VALUE

#define VLINK_VERSION_VALUE   VLINK_VERSION_CHECK(VLINK_VERSION_MAJOR, VLINK_VERSION_MINOR, VLINK_VERSION_PATCH)

The encoded 24-bit value for the current library version.

Equivalent to VLINK_VERSION_CHECK(VLINK_VERSION_MAJOR, VLINK_VERSION_MINOR, VLINK_VERSION_PATCH). Compare against the output of VLINK_VERSION_CHECK to gate code paths on a minimum library version at compile time.
