177# From the sched_setaffinity(2)'s man page:
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

195# sched_setaffinity prototypes:
196
197# ~~~~
