在窗口应用中使用printf，cout 等将输出重定向到console

AllocConsole();




HANDLE hin = ::GetStdHandle(STD_INPUT_HANDLE);


HANDLE hout = ::GetStdHandle(STD_OUTPUT_HANDLE);




int hcin = _open_osfhandle((intptr_t)hin,_O_TEXT);


FILE* fpin = _fdopen(hcin,"r");


*stdin = *fpin;




int hcout = _open_osfhandle((intptr_t)hout,_O_TEXT);


FILE* fpout = _fdopen(hcout,"wt");


*stdout = *fpout;




std::ios_base::sync_with_stdio();




std::cout << "test";




int i;


std::cin >> i;




std::cout << i;
