100 cpu

i've noticed that using peekmessage is just like using while(1) and totaly consumes the cpu, what's the best delay to put into the loop?
I was thinking sleep(0); what do you guys think?

The standard non-busy message loop is:

Code:

    BOOL bRet;
    MSG msg;

    while( (bRet = GetMessage( &msg, NULL, 0, 0 )) != 0)
    { 
        if (bRet == -1)
        {
            // handle the error and possibly exit
        }
        else
        {
            TranslateMessage(&msg); 
            DispatchMessage(&msg); 
        }
    }

If you want a delay in a PeekMessage() loop, yes you can use Sleep(1)(not Sleep(0)*) to give up the rest of the thread time slice when you have done whatever you need to do.

*Apparently, Sleep(0) will only yield to threads with the same or higher priorites, while Sleep(1) or above will yield to any thread.
