Dear all I am a quite new in Boost... Although I have experienced successfuly the smart_ptr library. Now, I would like to use IOSTREAM library. Even if the tutorial and User Guide are fine, they describe mostly how-to-write-xyz but very rarely how-to-use in practice. For instance I despearate to see an exmple on how-to-use the "line_wrapping_input_filter" example... Does someone can 1) tell me if there is somewhere example of how-to-use for end-user IOSTREAM features? 2) if someone as used the example and how... Best.
