探讨Console and port I/O 的主要作用(欢迎用过或没有用过但懂得的朋友)
SDK 中有很多流
These routines read and write on your console or on the specified port. The console I/O routines are not compatible with stream I/O or low-level I/O library routines. The console or port does not have to be opened or closed before I/O is performed, so there are no open or close routines in this category. In Windows NT and Windows 95, the output from these functions is always directed to the console and cannot be redirected.
