About WritePrivateProfileString and file operations

[Zhongli Xu]

Hi all,

I run some tests about mixed using WritePrivateProfileString and stand file
operations

Codes look like this:

GetPrivateProfileString(keyname, value);
fopen();
fprintf("# comments");
fclose();
WritePrivateProfileString(keyname, newvalue);

What I found in the file is that either WritePrivateProfileString operation
succeeded(newvalue has been written) or fprintf succeeded("#comments" shows
up in the file).

On windows hosts, there is no such problem.
Any suggestion or idea is welcomed.
Thanks.

Milo

I don't know if it's the same issue but i know there is a bug in wine's
implementation of WritePrivateProfileString.
See http://bugs.winehq.org/show_bug.cgi?id=5024

I currently use this hack http://bugs.winehq.org/attachment.cgi?id=6750 to
install the game. Maybe it helps for your app too, and maybe someone could pick
up this bug.

I think there is a problem with the check_sharing function in server/fd.c.

At the end of the function when it is checking existing_access with
the sharing variable it doesn't seem to care about what the caller is
requesting.

I think this is what is causing problems with the CreateFile call,
because the check_sharing function doesn't care if you don't even want
write access it will still check if you have the sharing bit.

I have created a patch that will hopefully solve the real problem
instead of the hack in WriteProfileString, I am not sure it is the
100% correct way to do it yet.
