[C/C++]WinSCard.dllを使ってPCSCでカードIDを取得する

Last updated at Posted at 2022-11-13

この記事は

FeliCaカードから製造番号（IDm）を読み取るためのC++,PowerShellのコード

  • SONY RC-S300
  • Windows 11 Home

Visual Studio CodeでC/C++開発する環境をつくる

  1. VSCodeはインストールして必要な拡張機能を入れるだけ。
  2. MSYSも入れて、コンソールからpacman -S --needed base-devel mingw-w64-x86_64-toolchain。必要な機能をインストールする。
  3. 1)～11)の番号で指定する。gcc, gdb, g++ の3つが必要。

コマンドプロンプトから実行

テストのために下記記事のソースで試した（zlibライセンス）

"C:\Windows\System32\WinSCard.dll"を使うために-lオプションで指定する

コマンドプロンプト
gcc qiita.cpp -lwinscard

VS Codeのtasks.jsonを変更する

VSCodeのF5で実行したときのタスクにも-lwinscardを付与するために、tasks.jsonに一行追加する

.vscode/tasks.json

    "tasks": [
        {
            "type": "cppbuild",

                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe",
