## ◆ clock()

clock_t clock | ( | void |  | ) |

Returns an approximation of processor time used by the program in Clocks

The value returned is the CPU time (ticks) used so far as a clock_t.

To get the number of seconds used, divide by CLOCKS_PER_SEC.

This is based on sys_time, which will wrap around every ~18 minutes. (unsigned 16 bits = 65535 / 60 / 60 = 18.2)

  sys_time, time()

## ◆ time()

time_t time | ( | time_t * | t | ) |

Converts clock() time to Seconds

Parameters

  t | If pointer t is not NULL, it's value will be set to the same seconds calculation as returned by the function.

The calculation is clock() / CLOCKS_PER_SEC

Returns: time in seconds
