fprintf(stdout,"Content-Type: application/doc\r\n\r\n");

int fd, filesize;
fd = _open( "e:\\chi.doc", _O_RDONLY|_O_BINARY );
filesize = _filelength(fd);

char* buf= new char[filesize];
_read(fd, buf, filesize);
_close(fd);
_setmode( _fileno( stdout ), _O_BINARY);
fprintf(stdout, buf);
delete []buf;
return 0;

这样不行，应该怎么写？？
