Difference of time in MilliSeconds - pls help urgent !!

[Skeletor]

Hi friends,
I am trying out a small function in which i want a time difference in milliseconds.
but am not able to do it.

i am using time_t tm;
than doing GetLocalTime(&tm); and using another instance but time_t does not show time in milliseconds.

I also tried with CTime and SYSTEMTIME but they give independant values and does not provide substraction facility.

pls help ... how to do this ?

Thanks.

Aloha,

you could use

clock()

Look in the MSDN, how to use it.
Its really nice.

hi,
try the GetTickCount function.
The difference between start of some code part and end would be the execution time in milliseconds.

You should use QueryPerformanceCounter() or QueryPerformanceFrequency() in stead.

If you try to benchmark a function, you dhould do something like this:

DWORD start, end;
DWORD dwCounter = 10000; // or some other value

QueryPerformanceCounter(&start);
while(dwCounter--)
   foo(); // call your function
QueryPerformanceCounter(&end);

double average = (end-start)/10000;
