| * g_app_info_launch_uris(). |
| * |
| * In contrast to g_app_info_launch_uris(), all processes created will |
| * always be run directly as children as if by the UNIX fork()/exec() |
| * calls. |
| * |
| * This guarantee allows additional control over the exact environment |
| * of the child processes, which is provided via a setup function |
| * @user_setup, as well as the process identifier of each child process |
| * via @pid_callback. See g_spawn_async() for more information about the |
