 * GSpawnChildSetupFunc:
 * @user_data: (closure): user data to pass to the function.
 *
 * Specifies the type of the setup function passed to g_spawn_async(),
 * g_spawn_sync() and g_spawn_async_with_pipes(), which can, in very
 * limited ways, be used to affect the child's execution.
 *
 * On POSIX platforms, the function is called in the child after GLib
 * has performed all the setup it plans to perform, but before calling
 * exec(). Actions taken in this function will only affect the child,
 * not the parent.
 *
 * On Windows, the function is called in the parent. Its usefulness on
 * Windows is thus questionable. In many cases executing the child setup
 * function in the parent can have ill effects, and you should be very
 * careful when porting software to Windows that uses child setup
 * functions.
 *
 * However, even on POSIX, you are extremely limited in what you can
 * safely do from a #GSpawnChildSetupFunc, because any mutexes that were
 * held by other threads in the parent process at the time of the fork()
 * will still be locked in the child process, and they will never be
 * unlocked (since the threads that held them don't exist in the child).
 * POSIX allows only async-signal-safe functions (see signal(7)) to be
 * called in the child between fork() and exec(), which drastically limits
 * the usefulness of child setup functions.
 *
 * In particular, it is not safe to call any function which may
 * call malloc(), which includes POSIX functions such as setenv().
 * If you need to set up the child environment differently from
 * the parent, you should use g_get_environ(), g_environ_setenv(),
 * and g_environ_unsetenv(), and then pass the complete environment
 * list to the `g_spawn...` function.

/**
 * GSpawnFlags:
 * @G_SPAWN_DEFAULT: no flags, default behaviour
 * @G_SPAWN_LEAVE_DESCRIPTORS_OPEN: the parent's open file descriptors will
 *     be inherited by the child; otherwise all descriptors except stdin,
 *     stdout and stderr will be closed before calling exec() in the child.
 * @G_SPAWN_DO_NOT_REAP_CHILD: the child will not be automatically reaped;
 *     you must use g_child_watch_add() yourself (or call waitpid() or handle
 *     `SIGCHLD` yourself), or the child will become a zombie.
 * @G_SPAWN_SEARCH_PATH: `argv[0]` need not be an absolute path, it will be
 *     looked for in the user's `PATH`.
 * @G_SPAWN_STDOUT_TO_DEV_NULL: the child's standard output will be discarded,
 *     instead of going to the same location as the parent's standard output.
 * @G_SPAWN_STDERR_TO_DEV_NULL: the child's standard error will be discarded.
 * @G_SPAWN_CHILD_INHERITS_STDIN: the child will inherit the parent's standard
 *     input (by default, the child's standard input is attached to `/dev/null`).
 * @G_SPAWN_FILE_AND_ARGV_ZERO: the first element of `argv` is the file to
 *     execute, while the remaining elements are the actual argument vector
 *     to pass to the file. Normally g_spawn_async_with_pipes() uses `argv[0]`
 *     as the file to execute, and passes all of `argv` to the child.
 * @G_SPAWN_SEARCH_PATH_FROM_ENVP: if `argv[0]` is not an abolute path,
 *     it will be looked for in the `PATH` from the passed child environment.
 *     Since: 2.34
 * @G_SPAWN_CLOEXEC_PIPES: create all pipes with the `O_CLOEXEC` flag set.
 *     Since: 2.40

 * Flags passed to g_spawn_sync(), g_spawn_async() and g_spawn_async_with_pipes().
