31 | /* This should be figured out by autoconf. |
32 | ||
33 | sysconf(_SC_CLK_TCK) is best, since it's the actual running kernel, not | |
34 | some compile-time CLK_TCK. On glibc 2.3.2 CLK_TCK (when defined) is in | |
35 | fact sysconf(_SC_CLK_TCK) anyway. | |
36 | ||
37 | CLK_TCK is obsolete in POSIX. In glibc 2.3.2 it's defined by default, | |
38 | but if you define _GNU_SOURCE or _POSIX_C_SOURCE to get other features | |
39 | then it goes away. */ | |
