Im trying to clock the time taken by two programs to execute, one uses win32 api's and other uses MFCs...I need to find the time in milli seconds or even better in micro seconds....
any idea how i shud go about it?
time function returns only in seconds(i need thousandth of a second also)

I am new to C programming so do help me.some probs may be very easy to ull..

thnx & regards

Simply time is divided by 1000 to get time microseconds

Hi,

There is a function:
clock_t clock(void);
in <time.h> which eturns number of clock ticks since process start, and there si a macro called CLK_TCK who defines the relation betwen clock tick and second (clock ticks per second).
So, if you want to calculate time elapsed betwen two events:


float timeElapsed;
clock_t clock0, clock1;
//event 1 happend:
clock0 = clock();
//time is running....
//event 2 happend:
clock1 = clock();
//time elapsed in seconds:
timeElapsed = (clock1 - clock0)/CLK_TCK;
/*just devide it with 1.000 to get it in miliseconds or
with 1.000.000 to get it in microseconds */

Try it, I think it will work :)
