ram - calling CreateFile, specifying FILE_ATTRIBUTE_TEMPORARY | FILE_FLAG_DELETE_ON_CLOSE -

Before I describe my problem, here is an explanation of this program which I am writing:

This is a C ++ application.

The purpose of my program is to create a file on RAM memory.

I've read that specifying FILE_ATTRIBUTE_TEMPORARYI FILE_FLAG_DELETE_ON_CLOSE this RAM will be loaded directly into memory when creating the file.

A blog that talks about it is:

I have created a mini-program, but it has not been achieved. Instead, it creates a file on the hard drive on the specified directory.

Here is my program:

  void main ()  

{

LPCWSTR str = L " C: \ temp.txt "; Handle FH = CreateFile (str, GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_TEMPORARY FILE_FLAG_DELETE_ON_CLOSE, NULL);

if (FH == INVALID_HANDLE_VALUE) {printf ("Could not open TWO.TXT"); Return; }

DWORD dwBytesWritten; (Lie Eye = 0; I & lt; 20000000; i ++) {WriteFile (FH, "This is a test for \ r \ n", 16, and dwBytesWritten, NULL)

} < / P>

return; }

I think there is a problem with the CreateFile function, but I can not fix it, please help me.

Larry Ostman also mentions:

If you have available memory , The memory manager will flush the file data into the disk. This affects a display, but your operation will succeed rather than fail.

Therefore, due to the limitation of memory the OS file creates the need to flush the data.
