This class contains a set of options for launching child processes,
such as where its standard input and output will be directed, the
argument list, the environment, and more.

While the 'GI.Gio.Objects.Subprocess.Subprocess' class has high level functions covering
popular cases, use of this class allows access to more advanced
options.  It can also be used to launch multiple subprocesses with
a similar configuration.

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

Typically you will build this variable by using 'GI.GLib.Functions.listenv' to copy
the process \'environ\' and using the functions 'GI.GLib.Functions.environSetenv',
'GI.GLib.Functions.environUnsetenv', etc.

As an alternative, you can use 'GI.Gio.Objects.SubprocessLauncher.subprocessLauncherSetenv',
'GI.Gio.Objects.SubprocessLauncher.subprocessLauncherUnsetenv', etc.

Pass an empty array to set an empty environment. Pass 'Nothing' to inherit the
parent process’ environment. As of GLib 2.54, the parent process’ environment
will be copied when 'GI.Gio.Objects.SubprocessLauncher.subprocessLauncherSetEnviron' is called.
Previously, it was copied when the subprocess was executed. This means the
copied environment may now be modified (using 'GI.Gio.Objects.SubprocessLauncher.subprocessLauncherSetenv',
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.

Sets the file path to use as the stderr for spawned processes.

If /@path@/ is 'Nothing' then any previously given path is unset.

The file will be created or truncated when the process is spawned, as
would be the case if using \'2>\' at the shell.

If you want to send both stdout and stderr to the same file then use
'GI.Gio.Flags.SubprocessFlagsStderrMerge'.

You may not set a stderr file path if a stderr fd is already set or
if the launcher flags contain any flags directing stderr elsewhere.

This feature is only available on UNIX.

Transfer an arbitrary file descriptor from parent process to the

in the parent when /@self@/ is freed.

By default, all file descriptors from the parent will be closed.
This function allows you to create (for example) a custom @/pipe()/@ or
@/socketpair()/@ before launching the process, and choose the target
descriptor in the child.

An example use case is GNUPG, which has a command line argument
--passphrase-fd providing a file descriptor number where it expects
the passphrase to be written.
