cant use of pthread_setschedparam on opensuse 11.4 with kernel 2.6.37.1-1.2

i am writing an application with c++ and NetBeans on opensuse 11.4 with kernel 2.6.37.1-1.2, (logged in as root)This application creates a thread and when runs

sched_param param;
param.__sched_priority = -1;
policy = SCHED_FIFO;
param.__sched_priority = 50;
result = pthread_setschedparam(m_thread,policy,&param);

result = 1(EPERM (not permitted)) why? thanks.

Look at this thread http://tinyurl.com/82bsbjh
you will notice if you never updated your kernel it will not work, so
double check after update and reboot what uname -r shows you, it should
show the version number 2.6.37.6-0.9, since you have 2.6.37.1-1.2 now I
suspect you are out of luck without update.

Solution run yast online update or run


sudo zypper patch

to apply the security updates for the kernel (and not only for that).

I hope I just read this the wrong way, does this mean you log into the
GUI as root and run the netbeans ide as root?
Never do this. Search the forums why not.
If I understood that wrong, ignore this.

That was not needed to upgrade the kernel, it would have been enough
just to apply the security update which comes on the normal update channel.

You can also use the normal update offline by downloading the delta rpm
for the kernel from the update repository.
But your problem is any way solved, I just wanted to make it clear.
