Hi all,

I was facing a problem like this.

Open a file handler by using the open function and made some changes on its, then close the file handler. Checked the file and it was updated.

let's say there is a second program (or routine) open the same file (for reading only), immediately after the one above, I found out that the file will be reverted back to its original contents.

This problem appear unless I issue sync command with system("sync") in between both of the programs(routines) above.

So what happen behind ? Why should I issued sync ? Isn't it the file was updated and save properly after I close the file handler in the first program ?
