268 | # From the sched_setaffinity(2)'s man page: |
269 | # ~~~~ | |
270 | # The CPU affinity system calls were introduced in Linux kernel 2.5.8. | |
271 | # The library interfaces were introduced in glibc 2.3. Initially, the | |
272 | # glibc interfaces included a cpusetsize argument. In glibc 2.3.3, | |
273 | # the cpuset size argument was removed, but this argument was | |
274 | # restored in glibc 2.3.4. | |
275 | # ~~~~ | |
276 | ||
277 | # In addition to that, some vendors ported the system call to 2.4 | |
278 | # kernels. | |
279 | ||
280 | # Furthermore, when the function first appeared, the MASK argument was | |
281 | # an unsigned long pointer, while later it was made into a cpu_set_t | |
282 | # pointer. Systems that have the cpu_set_t version also should have | |
283 | # the CPU_ZERO, CPU_SET, etc. macros. | |
284 | ||
