 178 # ~~~~
 179 # The CPU affinity system calls were introduced in Linux kernel 2.5.8.
 180 # The library interfaces were introduced in glibc 2.3.  Initially, the
 181 # glibc interfaces included a cpusetsize argument.  In glibc 2.3.3,
 182 # the cpuset size argument was removed, but this argument was
 183 # restored in glibc 2.3.4.
 184 # ~~~~
 185
 186 # In addition to that, some vendors ported the system call to 2.4
 187 # kernels.
 188
 189 # Furthermore, when the function first appeared, the MASK argument was
 190 # an unsigned long pointer, while later it was made into a cpu_set_t
 191 # pointer.  Systems that have the cpu_set_t version also should have
 192 # the CPU_ZERO, CPU_SET, etc. macros.
 193
 194 # All this mess means we have to cater for at least 3 different
 195 # sched_setaffinity prototypes:
 196
 197 # ~~~~
