file1.open("c:\\config.sys",ios::binary|ios::in,0); 如果open函数只有文件名一个参数,则是以读/写普通文件打开,即: file1.open("c:\\config.sys");<=>file1.open("c:\\config.sys",ios::in|ios::out,0); 另外,fstream还有和open()一样的构造函数,对于上例,在定义的时侯就可以打开文件了...

GetFile是一个高级例程,用于处理与从 FTP 服务器读取文件并在本地存储文件相关的所有开销。 仅检索文件数据或需要对文件传输进行密切控制的应用程序应改用OpenFile和CInternetFile::Read。 如果dwFlags 是 FILE_TRANSFER_TYPE_ASCII,则文件数据的转换也会将控制和格式化字符转换为 Windows 等效项。 默认传输是二进制模...
