 201 # From the sched_setaffinity(2)'s man page:
 202 # ~~~~
 203 # The CPU affinity system calls were introduced in Linux kernel 2.5.8.
 204 # The library interfaces were introduced in glibc 2.3.  Initially, the
 205 # glibc interfaces included a cpusetsize argument.  In glibc 2.3.3,
 206 # the cpuset size argument was removed, but this argument was
 207 # restored in glibc 2.3.4.
 208 # ~~~~
 209
 210 # In addition to that, some vendors ported the system call to 2.4
 211 # kernels.
 212
 213 # Furthermore, when the function first appeared, the MASK argument was
 214 # an unsigned long pointer, while later it was made into a cpu_set_t
 215 # pointer.  Systems that have the cpu_set_t version also should have
 216 # the CPU_ZERO, CPU_SET, etc. macros.
 217
 218 # All this mess means we have to cater for at least 3 different
 219 # sched_setaffinity prototypes:
 220
 221 # ~~~~
 222 #  int sched_setaffinity (pid_t pid, unsigned int len, unsigned long *mask);
 223 #  int sched_setaffinity (pid_t __pid, size_t __cpusetsize, const cpu_set_t *__cpuset);
