请问我想用fflush函数把标准输入stdin，输入到文件text中该怎么做？

#include <io.h> #include <stdlib.h> #include <stdio.h> int main( void ) { &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;FILE *DataFile; &nbsp;&nbsp;&nbsp;if( ( DataFile = fopen( "data", "w" ) ) == NULL ) &nbsp;&nbsp;&nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;puts( "Can't open file 'data'\n" ); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;exit( 1 ); &nbsp;&nbsp;&nbsp;} &nbsp;&nbsp;&nbsp;/* stdout now refers to file "data" */ &nbsp;&nbsp;&nbsp;if( -1 == dup2( fileno( DataFile ), 1 ) ) &nbsp;&nbsp;&nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;perror( "Can't _dup2 stdout" ); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;exit( 1 ); &nbsp;&nbsp;&nbsp;} &nbsp;&nbsp;&nbsp;puts( "This goes to file 'data'\r\n" ); &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;fflush( stdout ); &nbsp;&nbsp;&nbsp;fclose( DataFile );    &nbsp;&nbsp;&nbsp;return 0; }

谢谢啊，再问：fflush函数有fflush（text）的用法吗？也就是给fflush函数直接传一个地址参数！我试了下好像不行

应该将puts( "This goes to file 'data'\r\n" );改为printf( "This goes to file 'data'\r\n" );吧？？
