Websched_setaffinity () sets the CPU affinity mask of the thread whose ID is pid to the value specified by mask . If pid is zero, then the calling thread is used. The argument cpusetsize is the length (in bytes) of the data pointed to by mask . Normally this argument would be specified as sizeof (cpu_set_t) . If the thread specified by pid is not ...
WebJul 5, 2024 · The sched_setaffinity () takes two arguments. The first argument is the PID of the process whose processor affinity we want to set. The second argument is a tuple of integers representing the set of processors. We used {0,1,3} as the second argument. So, the operating system can bind the process to one of the processors in the tuple.
