• SDL_PROP_PROCESS_STDOUT_POINTER: a non-blocking SDL_IOStream that can be used to read output from the process, if it was created with SDL_PROP_PROCESS_CREATE_STDOUT_NUMBER set to SDL_PROCESS_STDIO_APP.
• SDL_PROP_PROCESS_STDERR_POINTER: a non-blocking SDL_IOStream that can be used to read error output from the process, if it was created with SDL_PROP_PROCESS_CREATE_STDERR_NUMBER set to SDL_PROCESS_STDIO_APP.
• SDL_PROP_PROCESS_BACKGROUND_BOOLEAN: true if the process is running in the background.
