c++ - Read and Write to Windows pipes in separate threads -


in program start thread redirect output console:

  while(true)   {      if (!readfile(hpiperead,lpbuffer,sizeof(lpbuffer),                                       &nbytesread,null) || !nbytesread)      {         if (getlasterror() == error_broken_pipe)            break; // pipe done - normal exit path.         else            displayerror("readfile"); // bad happened.      }       // display character read on screen.      if (!writeconsole(getstdhandle(std_output_handle),lpbuffer,                        nbytesread,&ncharswritten,null))         displayerror("writeconsole");   }

the problem is loop. possible to avoid run of loop making thread wait until appears in pipe?

the problem becomes more intense when there analogous thread writing.
