                    | Defined in header  <time.h> | ||
| #define CLOCKS_PER_SEC /*implementation defined*/ | ||
Expands to an expression (not necessarily a compile-time constant) of type clock_t equal to the number of clock ticks per second, as returned by clock().
[edit] Notes
POSIX defines CLOCKS_PER_SEC as one million, regardless of the actual precision of clock.
