Как в GUI приложении открыть консоль и назначить stdin,stdout,stderr?

#include <windows.h> 
#include <stdio.h>
#include <io.h>
#include <fcntl.h>

BOOL CreateConsole(void)
{
  FreeConsole();        //на всякий случай
  if ( AllocConsole() )
   {
         int hCrt = _open_osfhandle((long)
     GetStdHandle(STD_OUTPUT_HANDLE), _O_TEXT);
         *stdout = *(::_fdopen(hCrt, "w"));
     ::setvbuf(stdout, NULL, _IONBF, 0);
     *stderr = *(::_fdopen(hCrt, "w"));
     ::setvbuf(stderr, NULL, _IONBF, 0);
         return TRUE;
    }return FALSE;
}

int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
                     LPSTR lpCmdLine, int nCmdShow)
{
CreateConsole();
printf("WinMain with Console test\n");

MSG msg;
    while (GetMessage(&msg, NULL,  0, 0))
    {
       TranslateMessage(&msg);
       DispatchMessage(&msg); 
    }
   return TRUE;
}
