Hi, I want to be able to have users other than root run Pd with r-t scheduling. It looks like it can be done with setuid, but can anyone tell me how? cheers, Nick -- Dr Nick Fells, Music Department, University of Glasgow, Tel: +44 (0) 141-330 4096 Glasgow G12 8QQ Fax: +44 (0) 141-330 3518 UK. http://www.music.gla.ac.uk/~nick
