Thread: Multiple access to a file in C + + under Windows

Hello,

Accustomed to linux, and I am developing a small utility in Windows XP that can read a file while it is open read / write by another process. Let me explain:

- A program that I 1.exe imposed and I can not change continuously writing binary data in a file 1.txt

- I want to do a program 2.exe reading every 15 s if data are present in 1.txt.

When 1.exe is running, can not access 1.txt read or copy this file to a temporary file time to read it by 2.exe. Linux allows him!

I found a small utiliaire (unlocker, which allows a copy, but I wish we could do without using external program.

Thank you for your help.

Must go through the Win32 API management ficheirs which contains functions to open ficheir with end parameters of settings or FILE * iostream does not.

Otherwise see the side of boost:: filesystem
