            Bug ID: 16810
           Summary: __attribute__((__format__, N, M)) should have a
                    __wprintf__ version or the __printf__ version should
                    be able to handle wprintf-like functions too
           Product: clang
           Version: unspecified
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

If I try to do this:

    class A {
      int WriteWithFormat(const WChar *format, ...) __attribute__((__format__
(__printf__, 2, 3)));
    };

then I get this error:

    Format argument not a string type

and if I try to do this:

    class A {
        int WriteWithFormat (const WChar *format, ...)
__attribute__((__format__ (__wprintf__, 2, 3)));
    };

then I get this warning indicating it is useless:

    'format' attribute argument not supported: __wprintf__

Seems like one or the other should be supported (I prefer the second
personally).
