How to Decouple a Go Process from the Command Window and Hide the Console Window in Windows?

Decoupling a Process from the Command Window

In Go, you can create a child process using os.StartProcess(). However, by default, this process remains connected to the parent command window. To decouple the process and run it in the background, you need to modify its attributes.

In your code, you have set up the procAttr structure to redirect the file descriptors for the child process. However, it appears that you have omitted the necessary setting to hide the console window for Windows systems.

To hide the console window, add the following line to the procAttr.Sys member:

procAttr.Sys.HideWindow = true

However, you have mentioned that this results in a "panic to wrong memory pointer" error. This is most likely due to another issue in your code that is unrelated to the process decoupling.

To compile your program without linking to the Windows GUI subsystem and disabling the console window creation, use the following command:

go tool 8l -o output.exe -Hwindowsgui input.8

This will generate an executable that can be run in the background without a console window.
