 182 # From the sched_setaffinity(2)'s man page:
 183 # ~~~~
 184 # The CPU affinity system calls were introduced in Linux kernel 2.5.8.
 185 # The library interfaces were introduced in glibc 2.3.  Initially, the
 186 # glibc interfaces included a cpusetsize argument.  In glibc 2.3.3,
 187 # the cpuset size argument was removed, but this argument was
 188 # restored in glibc 2.3.4.
 189 # ~~~~
 190
 191 # In addition to that, some vendors ported the system call to 2.4
 192 # kernels.
 193
 194 # Furthermore, when the function first appeared, the MASK argument was
 195 # an unsigned long pointer, while later it was made into a cpu_set_t
 196 # pointer.  Systems that have the cpu_set_t version also should have
 197 # the CPU_ZERO, CPU_SET, etc. macros.
 198
 199 # All this mess means we have to cater for at least 3 different
 200 # sched_setaffinity prototypes:
 201
 202 # ~~~~
 203 #  int sched_setaffinity (pid_t pid, unsigned int len, unsigned long *mask);
