stdout redirection (2)

[jgtq3wj9jads]

Hi there,

I found this piece of code to redirect the stdout, but unfortunately I get a segment fault at the end of the program . Is there a way to get rid of that, I guess the error is in the destructor of the streambuf, but have no idea of that stuff...

Otherwise I take also another code, I simply need my gui to take the standard output and put it to a log element / so a function, which gets the chars, which I can use.

#include <iostream>
#include <ostream>
#include <sstream>
#include <streambuf>

class mystreambuf:
public std::basic_streambuf< char, std::char_traits< char > >
{

    typedef
    std::basic_streambuf< char, std::char_traits< char > >
    ::
    int_type
    int_type
    ;

    typedef std::char_traits< char > traits_t;


    int_type overflow( int_type c )
    {
        std::cerr << traits_t::to_char_type( c );

        // in your code write c to your QT widget hwever that
        // is done .

        return c;
    };


};

int main()
{
    mystreambuf mybuf;
    std::cout.rdbuf( &mybuf );

    std::cout << "here's some text";

    std::cout << "\n";

    std::cout.rdbuf();

    return 0;
};
