| 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 | # ~~~~ |

| 281 | # In addition to that, some vendors ported the system call to 2.4 |
| 282 | # kernels. |
