Re: libapl apl_exec results displayed as ?

[Chris Moller]

    apl_exec() can output to both stdout and stderr.
      
      I use:
      
    
        
          std::stringstream outbuffer;
        
             std::streambuf *coutbuf = std::cout.rdbuf();
        
             std::cout.rdbuf(outbuffer.rdbuf());
        
             std::stringstream errbuffer;
        
             std::streambuf *cerrbuf = std::cerr.rdbuf();
        
             std::cerr.rdbuf(errbuffer.rdbuf());
        
             execerr = apl_exec (cmd.toStdString ().c_str ());
        
             std::cout.rdbuf(coutbuf);
        
             std::cerr.rdbuf(cerrbuf);
        
             outString = QString (outbuffer.str ().c_str ());
        
             errString = QString (errbuffer.str ().c_str ());
