GetFileAttributesEx question...

Hi there everyone, I'm trying to learn the fundementals of File System manipulation. Right now I'm trying to get the creation and modification date of a file. How do I use the GetFileAttributesEx function. The function header looks like this:

Code:

---

BOOL GetFileAttributesEx(
  LPCTSTR lpFileName,                  // file or directory name
  GET_FILEEX_INFO_LEVELS fInfoLevelId,  // attribute class
  LPVOID lpFileInformation              // attribute information
);

---

This is straight off of the MSDN.

I understand that LPCTSTR lpFileName is, that one is easy.
What the heck is GET_FILEEX_INFO_LEVELS fInfoLevelId? I tried to create a simple variable of the GET_FILEEX_INFO_LEVELS type but I couldn't get anything out of it.
Also, I'm assuming that LPVOID lpFileInformation should just be a pointer to an empty buffer, right?

the second param is a pointer to a structure, take a look at this

http://msdn.microsoft.com/library/de...e_data_str.asp

The second parameter is a flag value which specifies which data to return. Currently, only GetFileExInfoStandard is supported which fills in a WIN32_FILE_ATTRIBUTE_DATA structure.

Code:

---

WIN32_FILE_ATTRIBUTE_DATA  wfad;

GetFileAttributesEx(TEXT("myfile.txt"), GetFileExInfoStandard, &wfad);

printf("Size of myfile.txt is %u\n", wfad.nFileSizeLow);

You can also use GetFileTime to retrieve the information you are seeking.
