常见的误解：文件必须在其最终的EOF字符 [英] Common misconception : Files have an EOF char at their end

问题描述

我在读卡特PC汇编语言，我看到了，这使我很困惑32页脚注这句话！

如果我们假设文件可能在他们到底有没有EOF（如书上说的）是一个正确的说法，那么我们怎么能揣摩出是文件的结束？

而且还出现了另一个问题：是否使用fseek的EOF去来回文件

I was reading "PC assembly language by Carter" and I saw this phrase in footnote of page 32 which made me so confused !
If we assume that files may have not EOF at their end (as the book says) is a correct statement, then how can we figure out where is end of a file ?
and it also arises another question : does fseek use EOF to go back and forth in file ?

推荐答案

PC => ^ Z：EOF

PC => ^Z : EOF

在奥尔德PC-天CTRL-Z是在EOF文件的信号。

in the olde PC-days the ctrl-Z was the signal in a file for EOF.

UNIX和其他现代系统下：看完stat.st_size落后之后，EOF发出信号

under UNIX and other modern systems: after reading behind the stat.st_size, EOF is signalled
