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);
