Thread: [Dev-C++] Timing My Application

Is there any function or command or program that, under windows, returns =
me how much time of CPU processing it spent? Must be someting in order =
or ms(milisseconds) or less.=20


Thankx.

Maybe I can do a little better.

clock in time.h returns the number of CPU clock 'ticks'
since the process started. Combine that with the macro
CLK_TCK which gives you the number of ticks per second you
can get the most accurate timer that your processor can
handle. And best of all it is ANSI compliant.

There is not any CLK_TCK as part of any C or C++ standard. You are probably
refering to CLOCKS_PER_SEC.

After a search on the web I came up to this:

Check your macro name there.


My Greek K&R 2 has it correctly.

Too fast answer :-)

What I meant to say is that clock() requires the application to get the
start value, so it can't retrieve all used time for a process. Also,
depending on implementation you really have to take care of overflow.
A third thing. It can't handle children. For that you need to call the
times() function.

The correct frequency of clock() is CLOCKS_PER_SEC.

Note that this is just wall time, and doesn't have anything with CPU time
to do.

No clock functions might be used, since they return wall time, and doesn't
take into account how much CPU the actual program got.

Under windows, you should use GetThreadTimes(), which will report amount
of time spent in user and kernel for a single thread, or GetProcessTimes()
that reports used time for a process.

Under unix, the corresponding call is getrusage().
