MSDN文档里也清楚地写着fflush on input stream is anextensionto the C standard(fflush操作输入流是对C标准的扩充)。当然,如果你毫不在乎程序的移植性,用fflush(stdin)也没什么大问题。以下是C99对fflush函数的定义: int fflush(FILE*stream); 如果stream指向输出流或者更新流(update stream),并且这个更新流 最近...
FileInputStream* fis =newFileInputStream("names.txt","r");cout<<"Adding names to the index"<<endl;std::vector<std::string> names;intx =0;while(true) {if(fis->eof()) {cout<<"No more names"<<endl;break; }if(x >=100) {break; } x++; BSONObj o;std::string* name = fis->...
直接从JDK接口文档入手,以FileInputStream为例,JDK接口文档给出了明确的说明: 使用FileInputStream的read方法读取文件时,当返回-1就表明读到了文件末尾,如果期间出现IO异常,则会抛出一个IOException。而对于EOF文件结束符,其实是不存在的。在Linux系统之中,EOF根本不是一个字符,而是当系统读取到文件结尾,所返...
read(2) for the file descriptor associated with the input stream; the results will be undefined and very probably not what you want. # 以下来自man 2 read On success, the number of bytes read is returned (zero indicates end of file), and the file position is advanced by this number. It...
java.io.EOFException: unexpected EOF read on the socket 异常表明在读取数据时,到达了数据流的末尾(EOF, End Of File),但这在预期的数据流结束之前发生了。这通常是因为网络连接被对方关闭或者出现了数据传输中断,导致客户端或服务器在预期接收到更多数据时,却已经读到了流的末尾。
