 152 # From the sched_setaffinity(2)'s man page:
 153 # ~~~~
 154 # The CPU affinity system calls were introduced in Linux kernel 2.5.8.
 155 # The library interfaces were introduced in glibc 2.3.  Initially, the
 156 # glibc interfaces included a cpusetsize argument.  In glibc 2.3.3,
 157 # the cpuset size argument was removed, but this argument was
 158 # restored in glibc 2.3.4.
 159 # ~~~~
 160
 161 # In addition to that, some vendors ported the system call to 2.4
 162 # kernels.
 163
 164 # Furthermore, when the function first appeared, the MASK argument was
 165 # an unsigned long pointer, while later it was made into a cpu_set_t
 166 # pointer.  Systems that have the cpu_set_t version also should have
 167 # the CPU_ZERO, CPU_SET, etc. macros.
 168
 169 # All this mess means we have to cater for at least 3 different
 170 # sched_setaffinity prototypes:
 171
 172 # ~~~~
 173 #  int sched_setaffinity (pid_t pid, unsigned int len, unsigned long *mask);
