Scanf Bug

Scanf seems to not work correctly.

How to reproduce the bug:
1) install in wine the Dev-cpp
2) write a simple program that performs at least two scanf (see attachment)
3) run it...

expected result:
each scanf read a value from the keyboard

actual result:
the first scanf works fine. Subsequent read from keybord not

try putting an fflush(stdin);
before doing the second scanf and try it in wine.

(In reply to comment #1)

This is one of the first things I've tried. Anyway:
1) the example do have the fflush(stdin) before reading from the stdin
2) the same program works fine if compiled under windows or under linux

For these reason, I think that the bug is still open and needs to be fixed :)

Anyway, thank you for your proposal!

The patch caused this bug:

msvcrt: Fix ^Z handling in text mode.

When I commented out this block of code:
+  if (MSVCRT_fdesc[fd].wxflag & WX_READEOF) {
+     MSVCRT_fdesc[fd].wxflag |= WX_ATEOF;
+     TRACE("already at EOF, returning 0\n");
+     return 0;
+  }

bug disappeared (but msvcrt tests fail).

That's interesting.

Can a test case be written for this, using pipes or something?

When we fix this, let's be careful to not cause a regression
in bug 9894.

Sorry for the breakage.  According to 
http://www.winehq.org/pipermail/wine-patches/2008-February/049557.html
this also affects the MinGW port of git-fetch-pack, so comfirming.
His patch was right but not complete; I've added a test
and the missing bit, and submitted it as
http://www.winehq.org/pipermail/wine-patches/2008-February/049807.html
Let me know if that doesn't resolve everything.
