194# From the sched_setaffinity(2)'s man page:
195# ~~~~
196# The CPU affinity system calls were introduced in Linux kernel 2.5.8.
197# The library interfaces were introduced in glibc 2.3. Initially, the
198# glibc interfaces included a cpusetsize argument. In glibc 2.3.3,
199# the cpuset size argument was removed, but this argument was
200# restored in glibc 2.3.4.
201# ~~~~
202
203# In addition to that, some vendors ported the system call to 2.4
204# kernels.
205
206# Furthermore, when the function first appeared, the MASK argument was
207# an unsigned long pointer, while later it was made into a cpu_set_t
208# pointer. Systems that have the cpu_set_t version also should have
209# the CPU_ZERO, CPU_SET, etc. macros.
210

212# sched_setaffinity prototypes:
213
214# ~~~~
215# int sched_setaffinity (pid_t pid, unsigned int len, unsigned long *mask);
