Thanks for the response.

Well, there's the rub.  Using Visual Studio (2005) I made a slightly  
different program:

  // temp.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include "Wtypes.h"
#include "winuser.h"
#include "winbase.h"


int _tmain(int argc, _TCHAR* argv[])
{ HANDLE handle;
/*
        handle = CreateFile(_T("foo"), GENERIC_READ|GENERIC_WRITE, NULL, NULL,
                CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);

        CloseHandle(handle);
*/
        FILE *fp;

        fp = fopen("foo", "w");
        if (fp == NULL) {
                fprintf(stderr, "fopen failed\n");
                exit(1);
        }
        fclose(fp);

        return 0;
}

Running the compiled result of this under cygwin yields:

georgn@up /cygdrive/c/Users/georgn/Documents/Visual Studio 2005/
Projects/debug
$ ls -l
total 776
-rwx------+ 1 georgn         None      0 Aug 27 10:52 foo
-rwx------+ 1 Administrators None  40960 Aug 27 10:52 temp.exe
-rwx------+ 1 Administrators None 319952 Aug 27 10:52 temp.ilk
-rwx------+ 1 Administrators None 429056 Aug 27 10:52 temp.pdb


And the result is the same whether I use the CreateFile or fopen  
interfaces.

Is the C runtime that various folks refer to subject to change from  
system to system?  Is there more than one?  Is it a .dll or some  
static wad that gets linked into the .exe?  (Sorry, I'm a long time  
unix hack and this windows stuff is making me mental).

I'm thinking that my next experiment will be to add a sleep, pause,  
whatever and using something like process exploder to learn more.
