SubprocessLauncher.setEnviron

Replace the entire environment of processes launched from this launcher with the given 'environ' variable.

Typically you will build this variable by using [glib.global.listenv] to copy the process 'environ' and using the functions [glib.global.environSetenv], [glib.global.environUnsetenv], etc.

As an alternative, you can use [gio.subprocess_launcher.SubprocessLauncher.setenv], [gio.subprocess_launcher.SubprocessLauncher.unsetenv], etc.

Pass an empty array to set an empty environment. Pass null to inherit the parent process’ environment. As of GLib 2.54, the parent process’ environment will be copied when [gio.subprocess_launcher.SubprocessLauncher.setEnviron] is called. Previously, it was copied when the subprocess was executed. This means the copied environment may now be modified (using [gio.subprocess_launcher.SubprocessLauncher.setenv], etc.) before launching the subprocess.

On UNIX, all strings in this array can be arbitrary byte strings. On Windows, they should be in UTF-8.
