Hi,
We are interested in realtime application and CPU affinity.
After googling pthread_setaffinity_np, I have found that it appeared in 7.2.
But I cannot find it by man command.
Does anyone know the status of CPU affinity function in FreeBSD or
useful links about it?
I have found the pointer about a command,
http://segfault.in/2010/09/how-to-set-cpu-affinity-for-a-process-in-freebsd/
Man pages are available on-line.
http://www.freebsd.org/cgi/man.cgi?query=pthread_setaffinity_np&apropos=0&sektion=0&manpath=FreeBSD+8.2-RELEASE&format=html
And the actual functions that should be used on modern FreeBSD are
cpuset_setaffinity and cpuset_getaffinity.
