Hi, I''m trying to change the scheduling policy of my rt-process to FIFO. I''ve got an Error and after looking into the manpage I''ve found out that the process has to be a root process (with super user privelege). But can someone help me how to do this? I''m root when executing the program and I couldn''t find a syscall for this? thanx alot!

That''s enough, as long as you don''t drop privileges anywhere. Check what the error code is (probably errno or the return value) and see what the man page says about that.

It may be, for example, that your kernel doesn''t support it, rather than lack of permissions.
