python以及c++中怎么把stdout恢复为标准输出

python中

sys.stdout = sys.__stdout__;

sys.stderr = sys.__stderr__;

 

c++中windows版为：

freopen( "CON", "w", stdout ); （参见链接）

linux应该为

freopen( "/dev/tty", "w", stdout );

#include 
#include 

void main(void)
{
   FILE *stream ;
   if((stream = freopen("file.txt", "w", stdout)) == NULL)
      exit(-1);

   printf("this is stdout output/n");

   stream = freopen("CON", "w", stdout);

   printf("And now back to the console once again/n");
}
