How can I detach a Go process from its parent in Windows using `StartProcess()`?

Decoupling a Process in Go

To detach a process created using StartProcess() from its parent (in this case, a command-line prompt), one can leverage the -Hwindowsgui linker option provided by the Go toolchain.

Original Code

The provided Go code attempts to create a decoupled process using StartProcess(), with the following configuration:

<code class="go">var procAttr os.ProcAttr 
procAttr.Files = []*os.File{nil, nil, nil}</code>

While adding procAttr.Sys.HideWindow = true aims to hide the window associated with the process, it leads to the error "panic" to wrong memory pointer.

Solution

The proper solution is to use the -Hwindowsgui linker option when compiling the Go program. This option disables creation of a console window for the process upon execution:

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

By invoking the -Hwindowsgui linker option, the process is created without a console window, effectively decoupling it from the command prompt. This allows the process to run in the background independent of the parent process.
