GetProcessImageFileNameで、そのプロセスのプロセス名というか、実行ファイルのパスを取得できる。
GetProcessImageFileNameA function (psapi.h) - Win32 apps | Microsoft Docs
C++でプロセス名からプロセスIDを取得する - 備忘録
GetProcessImageFileName()で取得できるパス名について – プログラミング – Home
最初、QueryFullProcessImageNameを使ってたのだが、どうも失敗する。
しかもなぜかERROR_INSUFFICIENT_BUFFERで。
管理者権限かなとも思ったが、関係ない模様。
なので、
GetProcessImageFileNameでやってみた。

まあ、開けないのはしょうがないとして、開けるものは取得できた。
ただし、パスがデバイス形式なのは注意。
