I get a 388bytes memory leak each time I call the CreateProcess() function.
Here is my following code:

void main(int argc, char* argv[])
{
STARTUPINFO si; // = { sizeof(si) };
PROCESS_INFORMATION pi;

while (true) {
ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );

if(CreateProcess(NULL,"C:\\temp\\TestFile.exe", NULL, NULL, FALSE, 0,
NULL, NULL, &si, &pi))
{
WaitForSingleObject(pi.hProcess, INFINITE);

DWORD ExitCode;
GetExitCodeProcess(pi.hProcess, &ExitCode);

CloseHandle(pi.hProcess);
CloseHandle(pi.hThread);
}
else
{
cout << "Error CreateProcess()..." << endl;
}
}
}

I use Visual .Net and Windows 2000 Professional. With XP or XP Embedded, the
problem is still here.

Can anybody tell me what is the trouble with my code?

The code looks just fine. How do you measure those 388 bytes?

With Purify

By the way, you're NOT supposed to pass a constant string to CreateProcess.

You are right...

But I write here the simplest code I could wrote. My leak is still present
if I replace my constant string by a LPTSTR.

Am I the only one to get a leak with this code, or has anybody the same
trouble?

My question is: It is the code itself, the configuration of the compiler, or
something else I don't understand. I have this leak with different computer,
and I also compile with different computer.

If you run this simple code, you will see the memory for this application
that will increase with the task manager. No need to use purify or anything
else to test.
