How to check how many bytes my application wrote and read from Disk?

Question

I don't know if I didn't use the right words to search on web but I didn't find the solution to watch how much my application already read and wrote on disk.

Some one can help me with this ?

tks

If some one need the function sign.

type
  _IO_COUNTERS = record
    ReadOperationCount : LONGLONG;
    WriteOperationCount : LONGLONG;
    OtherOperationCount : LONGLONG;
    ReadTransferCount : LONGLONG;
    WriteTransferCount : LONGLONG;
    OtherTransferCount : LONGLONG;
  end;
  TIoCounters = _IO_COUNTERS;

  function GetProcessIoCounters(hProcess: THandle; var lpIoCounters: TIoCounters): BOOL; stdcall external kernel32;

Although not a programming question, this is something that many programmers need to know how to do, to fix their programs. So let's not close this one.... — Chris Thornton, Jan 28 '11 at 21:51
If programmers want to know then they can look on superuser where this belongs — David Heffernan, Jan 28 '11 at 21:54
SaCi, please re-phrase your question otherwise it'll get closed. I have withdrawn my off-topic answer about ProcessMonitor. — Chris Thornton, Jan 28 '11 at 22:01
@David I think this is a perfectly valid profiling question! Programming is not only about typing code. When I use a compiler a debugger or a profiler I'm USING a software but that doesn't mean I'm not programming. — Mauricio, Jan 28 '11 at 22:14
ok maybe you are right. Question would benefit from more detail though. — David Heffernan, Jan 28 '11 at 22:17
@David sure; after all he was looking for an api, so.. more programming than ever :) — Mauricio, Jan 28 '11 at 22:31
I don't think he was specifically asking for an API as opposed to simply an answer of how to do it. — Loren Pechtel, Jan 29 '11 at 01:03
Non programming answer: check performance in windows tools like performance monitor. — Warren P, Jan 30 '11 at 02:25

if you want get this info programmatically you can use the GetProcessIoCounters function. Another alternative is using the WMI , see the Win32_Process class and check these properties (WriteOperationCount, WriteTransferCount, ReadTransferCount, ReadOperationCount).

I think is this that I was looking for. I'll check it after confirming I accept the answer. Tks – Rodrigo Farias Rezino Jan 28 '11 at 21:59
