Please check this program...

Hi All,

> I have written a program that creates a child process and calculates the child process memory usage

> Please tell me what is an alternative for "Sleep(20000);" ( i need to wait till the child process finishes its execution)

> and i have no idea about the output, on my console (i,e output consists of numbers)


my Output:****************************


PagefileUsage : 0

PeakPagefileUsage : 3420160

cb : 40

PageFaultCount : 2665

PeakWorkingSetSize : 8192000

WorkingSetSize : 36864

Done.



my Code:*****************************

int main()
{
STARTUPINFO si;
PROCESS_INFORMATION pi;


GetStartupInfo(&si);


CreateProcess ("E:\\MemoryUsageProgram.exe", // Name of app to launch
NULL,
NULL,
NULL,
FALSE,
0,
NULL,
NULL,
&si,
&pi);


Sleep(20000);



PROCESS_MEMORY_COUNTERS PProcessMemoryCounters;

GetProcessMemoryInfo (pi.hProcess,
&PProcessMemoryCounters,
sizeof(PProcessMemoryCounters));


cout<<"\n"
<<"PagefileUsage: "<<PProcessMemoryCounters.PagefileUsage<<endl
<<"PeakPagefileUsage: "<<PProcessMemoryCounters.PeakPagefileUsage<<endl
<<"cb: "<<PProcessMemoryCounters.cb<<endl
<<"PageFaultCount: "<<PProcessMemoryCounters.PageFaultCount<<endl
<<"PeakWorkingSetSize: "<<PProcessMemoryCounters.PeakWorkingSetSize<<endl
<<"WorkingSetSize: "<<PProcessMemoryCounters.WorkingSetSize<<endl;


cout<<"\nDone.\n";

return 0;
}


>Please suggest me alternative instruction for "Sleep(20000);" (to wait till child process is finished)

> and about the output, currently I'm assuming the output (numerical values) are in BYTES.

THANK YOU IN ADVANCE...

How can I wait until a process ends?

> thanks!! for the instruction alternative to "Sleep" , it helped me a lot...

>could u please tell me about the output .... is it in BYTES [especially for PeakPagefileUsage ( PProcessMemoryCounters.PeakPagefileUsage ) for the code above]...
