These functions let applications spawn a process in another copy of their sandbox.
To monitor spawned processes, use the “spawn-exited” signal.
The underlying portal is org.freedesktop.portal.Flatpak.
void xdp_portal_spawn (XdpPortal *portal,const char *cwd,const char * const *argv,int *fds,int *map_to,int n_fds,const char * const *env,XdpSpawnFlags flags,const char * const *sandbox_expose,const char * const *sandbox_expose_ro,GCancellable *cancellable,GAsyncReadyCallback callback,gpointer data);
Creates a new copy of the applications sandbox, and runs a process in, with the given arguments.
The learn when the spawned process exits, connect to the “spawn-exited” signal.

pid_t xdp_portal_spawn_finish (XdpPortal *portal,GAsyncResult *result,GError **error);
Finishes the spawn request, and returns the pid of the newly spawned process.
void xdp_portal_spawn_signal (XdpPortal *portal,pid_t pid,int signal,gboolean to_process_group);
Sends a Unix signal to a process that has been spawned
by xdp_portal_spawn().
Flags influencing the spawn operation and how the new sandbox is created.
