Hi all,

I want to use a single std::stringbuf for writing (by a std::ostream)
and for reading (by a std::istream), concurrently in two threads.
This came to my mind, because the code for reading should be as with any other istream and cannot be changed.

Now my problem is, that a do not get any data in the reading loop
std::ofstream tempfile("test. pdf",
std::ios_base:: out...
