If an error occurs, like the user lacks permission to change the priority, an error of level E_WARNING is generated and &false; is returned. Otherwise, &true; is returned. proc_nice will only exist if your system has 'nice' capabilities. 'nice' conforms to: SVr4, SVID EXT, AT&T, X/OPEN, BSD 4.3. This means that proc_nice is not available on Windows. proc_nice is not related to proc_open and its associated functions in any way.
