Spawn.sync

Executes a child synchronously (waits for the child to exit before returning). All output from the child is stored in @standard_output and @standard_error, if those parameters are non-%NULL. Note that you must set the %G_SPAWN_STDOUT_TO_DEV_NULL and %G_SPAWN_STDERR_TO_DEV_NULL flags when passing %NULL for @standard_output and @standard_error.

If @exit_status is non-%NULL, the platform-specific exit status of the child is stored there; see the documentation of g_spawn_check_exit_status() for how to use and interpret this. Note that it is invalid to pass %G_SPAWN_DO_NOT_REAP_CHILD in @flags.

If an error occurs, no data is returned in @standard_output, @standard_error, or @exit_status.

This function calls g_spawn_async_with_pipes() internally; see that function for full details on the other parameters and details on how these functions work on Windows.
