272# ~~~~
273# The CPU affinity system calls were introduced in Linux kernel 2.5.8.
274# The library interfaces were introduced in glibc 2.3. Initially, the
275# glibc interfaces included a cpusetsize argument. In glibc 2.3.3,
276# the cpuset size argument was removed, but this argument was
277# restored in glibc 2.3.4.
278# ~~~~
279
280# In addition to that, some vendors ported the system call to 2.4
281# kernels.

283# Furthermore, when the function first appeared, the MASK argument was
284# an unsigned long pointer, while later it was made into a cpu_set_t
285# pointer. Systems that have the cpu_set_t version also should have
286# the CPU_ZERO, CPU_SET, etc. macros.
