procciao 0.13

A library for killing processes/subprocesses the most gracefully way possible

A library for killing processes/subprocesses the most gracefully way possible

pip install procciao

Tested against Windows 10 / Python 3.11 / Anaconda

The attempts to kill processes go from the most gracefully to the most forcefully

1. https://github.com/ElyDotDev/windows-kill SIGINT/SIGBREAK (DLL/EXE)
2. powershell SIGINT/SIGBREAK/CLOSE
3. taskkill
