SiddiqSoft.WinProcessInfo 1.0.4

WinProcessInfo : Sample Windows process information

Objective

Provide for a simple "stats" for a daemon/service without the heft of the full process information library.

• Minimal footprint
• Serializer for nlohmann::json (you must include the library prior to this header file)
• Serializer for std::format (if supported by your compiler)

Requirements

• We use nlohmann::json only in our tests and the library is aware to provide a conversion operator if library is detected.
• We use std::format if present

Usage

• Use the nuget SiddiqSoft.WinProcessInfo
• Copy paste..whatever works.

Interface

WinProcessInfo
- uptime()
- snapshot()
- serializer for nlohmann::json
- serializer for std::format

Example

#include "gtest/gtest.h"
#include <format>
#include "nlohmann/json.hpp"
#include "siddiqsoft/WinProcessInfo.hpp"

TEST(examples, Example2)
{
   try {
      siddiqsoft::WinProcessInfo procInfo;

      // We must perform the snapshot to obtain memory and thread usage
      procInfo.snapshot();

      // tip: do not use brace-init/assignment as it will create an array instead of object!
      nlohmann::json info(procInfo);

      std::cerr << info.dump() << std::endl;
      EXPECT_EQ(GetCurrentProcessId(), info.value("processId", 0));
   }
   catch (std::exception& e) {
      EXPECT_TRUE(false) << e.what(); // if we throw then the test fails.
   }
}
