[Bug 16923] New: sscanf function missing hh modifier

[wine-bugs at winehq.org]

http://bugs.winehq.org/show_bug.cgi?id=16923

           Summary: sscanf function missing hh modifier
           Product: Wine
           Version: 1.1.10
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: msvcrt
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: pcjc2 at cam.ac.uk


The sscanf function in the Wine msvcrt runtime doesn't support the "hh"
modifier, as described here:

http://www.opengroup.org/onlinepubs/009695399/functions/sscanf.html

I've not tested or read the source thoroughly enough to see if any other of the
standard modifiers are missing from the Wine implementation.

Since I'm not sure whether Micosoft's msvcrt.dll supports this modifier (and
have no Windows box working to test at the moment), I appreciate this might be
closed "not a bug" if the behaviour is infact compatible with Microsoft's.

I'm developing applications on linux, cross-compiling and using wine to test.
The lack of an hh modifier caused memory corruption and some strange behaviours
in the app. We've changed our code to avoid the problem, but I thought I'd do
due diligence and mention it here in case it turned out to be a problem for you
guys.

Best regards

Peter Clifton
