求教:关于一个文件偏移量问题
在advanced programming in the unix environment那本书16.4节中,(原版影印的520页),有这样一句话:To keep this example small,we have set the size of each ptr field to four ASCII characters,and the number of hash chains is three.Since each ptr is a file offset,a four character field limits the total size of the index file and data file to 10,000 bytes.请问这里为什么是10,000 字节?多谢了!
------解决方案--------------------我想他的4个ASCII字符的意思不是说四个字节,而是说4个 '0 '- '9 '的数字,最小值是0000,最大值是9999,也就是10000个数据。
