272# From the sched_setaffinity(2)'s man page:
273# ~~~~
274# The CPU affinity system calls were introduced in Linux kernel 2.5.8.
275# The library interfaces were introduced in glibc 2.3. Initially, the
276# glibc interfaces included a cpusetsize argument. In glibc 2.3.3,
277# the cpuset size argument was removed, but this argument was
278# restored in glibc 2.3.4.
279# ~~~~
280
281# In addition to that, some vendors ported the system call to 2.4
282# kernels.
283
284# Furthermore, when the function first appeared, the MASK argument was
285# an unsigned long pointer, while later it was made into a cpu_set_t
286# pointer. Systems that have the cpu_set_t version also should have
287# the CPU_ZERO, CPU_SET, etc. macros.
288
289# All this mess means we have to cater for at least 3 different
290# sched_setaffinity prototypes:
