Creating a Console Windows for a Win32 program in windows subsystem so that you can printf again

create-console.c

// adapted from c++ on stackoverflow: https://stackoverflow.com/a/57210516/5974331

// opens a new console windows for the current process
// returns 1 on success
int CreateConsole() {
    if (!AllocConsole()) {
        return 0;
    }
    FILE *fDummy;
    freopen_s(&fDummy, "CONIN$", "r", stdin);
    freopen_s(&fDummy, "CONOUT$", "w", stderr);
    freopen_s(&fDummy, "CONOUT$", "w", stdout);
    fflush(stdin);
    fflush(stderr);
    fflush(stdout);
    return 1;
}

// usage example:

int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PWSTR pCmdLine, int nCmdShow)
{
    if (!CreateConsole()) {
        return 1;
    }
    printf("I will show up on the new console\n");
    
    // rest of implementation of windows program
    // createwindows / GetMessage / etc
}
