           Summary: tmpfile() write, seek(0) and read does not return same
                    data
           Product: Wine
           Version: unspecified
          Platform: All
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: lkcl(a)lkcl.net


ok this is tested from python (import os) so it _could_ be done a little
simpler - like... using c.  didn't want to forget about it so am raising it
here.

this is the mode opening a tmpfile:

 fixme:msvcrt:MSVCRT__sopen : pmode 0x1464e0 ignored

$ ./python.exe -i
Python 2.5.2 (r252:60911, Jan 15 2009, 23:28:55) [gcc] on win32

> > > import os

> > > f.write("hello\n")
> > > f.flush()
> > > f
> > > <open file '<tmpfile>', mode 'w+b' at 0x001B34E8>
> > > f.tell()
> > > 6L
> > > f.seek(0)
> > > f.tell()
> > > 0L
> > > f.read()
> > > ''

it's as if it's impossible to read from the tmpfile.  which kinda defeats the
object of having one :)

c:\windows\temp exists but c:\windows\tmp does not.
