Control CPU usage of a program?
 

Hi all,

I am writing programs of algorithms using C++ and C. When I run the
programs,
I found the programs take 100 percent of the CPU usage and I cannot run
any other program.
How to control the CPU usage percentage?
For example, let the program take 30 percent of the CPU usage? Thanks!

BTW, the circumstance is Windows 2k and XP.

Best regards,
Robert

There is no way in C++ to do that. The C++ language is specified
without considering any other programs. All that is given to the
host operating system to control.

Then go to 'comp.os.ms-windows.programmer.win32' or any relevant
newsgroup from the 'microsoft.public.*' hierarchy.

Off-topic. Please see:

Yes there is! You can do most things with C++ but how it is done it is
Off topic for this NG.

Not really. AFAIK the standard just specifies the language it does not
specify other programs or OS

What if there is no host operating system? What if this "program" is
the OS? IF the program is the OS then it can clearly control the CPU
loading.

We agree here. This is a Windows programing problem. I am sure that he
will be able to implement something in C++ to solve the problem he is
just asking in the wrong place.
