c++ - I've created a new console in win32 window-only app, console is created but nothing gets print on it -

this code compiled -mwindows under gcc , there no winapi error message.

#include <windows.h> #include <stdio.h>  int winapi winmain(hinstance hinstance, hinstance, lptstr, int ncmdshow) {   allocconsole();   printf("%s\n", "sample text");   return 0; } 

result console black empty, no text, no error message.

use:

freopen("conout$", "wb", stdout); 

to reopen stdout after have created console. if plan on using input too, need:

freopen("conin$", "rb", stdin); 

and stderr may need opening too:

freopen("conout$", "wb", stderr);
