Function glib::spawn_async

pub fn spawn_async(
    working_directory: Option<impl AsRef<Path>>,
    argv: &[&Path],
    envp: &[&Path],
    flags: SpawnFlags,
    child_setup: Option<Box<dyn FnOnce() + 'static>>
) -> Result<Pid, Error>

Executes a child program asynchronously.

See g_spawn_async_with_pipes() for a full description; this function simply calls the g_spawn_async_with_pipes() without any pipes.

You should call g_spawn_close_pid() on the returned child process reference when you don’t need it any more.

If you are writing a GTK application, and the program you are spawning is a graphical application too, then to ensure that the spawned program opens its windows on the right screen, you may want to use #GdkAppLaunchContext, #GAppLaunchContext, or set the DISPLAY environment variable.

Note that the returned @child_pid on Windows is a handle to the child process and not its identifier. Process handles and process identifiers are different concepts on Windows.
