Checking a files creation date??

**Iron Jay** · 10-13-2003

Hey everyone,

I just started learning c++ a couple of weeks ago for a specific project so im not completely confident with it.

The program is currently being created in c++builder but will eventually be run in Linux. It allows the user to select a number of files (.txt files) from a dialog box, the file locations are then stored in an array and displayed in a listbox.

I need to check what date all the files (selected by the user) were created on. I was wondering if anyone could help me out with how to do this?

thanks.

$ man 2 stat (to get file status)
and
$ man 2 utime (to change file time)

thats Jaguar but i'm looking for a c++ function or something similar to check the file creation dates for me.
Can you help me out with that at all?

There is no "one-set-function" to return a file creation date, as far as I'm aware. In fact, I'm not certain if you can even determine a file creation date.

Your "closest" option would probably be the file change date, as that requires more than content change to be updated; file attributes need to be modified.

Well in Linux / Unix / any POSIX operating system, use stat() as mentioned already

If you want a win32 function, use

Code:

BOOL GetFileTime(
  HANDLE hFile,
  LPFILETIME lpCreationTime,
  LPFILETIME lpLastAccessTime,
  LPFILETIME lpLastWriteTime
);

> but i'm looking for a c++ function
No such thing - functions don't care what language they're written in, or what language the caller is written in.
C++ is about classes and encapsulation of data - when it gets down to the gritty detail of actually getting some work done, it's all about functions.
