 ## Features
 - Support both **32bit** (Win32) & **64bit** (x64) Windows
-- Support both ```SIGBREAK``` (Ctrl + Break) and ```SIGINT``` (Ctrl + C) Signals
+- Support `SIGBREAK` (Ctrl + Break), `SIGINT` (Ctrl + C), and `SIGCLOSE` (click close button) Signals.
 - A library that could be used directly (#include), As a static library (.lib) and a dynamic library (.dll)
 - Prebuilt binaries and libraries
