clock
The clock function determines how much processor time is used by the calling process
up to the point that the process invokes the clock function.
Return Value
is the process execution time of the CPU for this process. The time is given in
microseconds.
Usage Guidelines
•
The clock function returns the time in microseconds. This returned value can be
divided by CLOCKS_PER_SEC to convert it to seconds. The CLOCKS_PER_SEC
macro is defined in the header timeh.
#include <timeh>
clock_t clock(void);
