什么是`16 longs`的含义和`110 words`，当从文件中读取所述位 [英] What is the meaning of `16 longs` and `110 words`, when reads the bits from a file

问题描述

我想读 PUD 文件格式，属于魔兽争霸2 游戏地图。

在文件结构的解释，有小的短语我不明白它。

这是什么意思（ 16多头， 110字）的 ？

下面是一个例子

  

16多头------->单位和允许的建筑。 （16名球员）

这意味着 16多头 = 16 * 4字节= 64 或 16 * 32位= 512 或其它。结果
也有同样的事情 110字。

解决方案

他们指的是C型上的特定结构。在C，长是一个类型的变量。其大小而作为编译器的功能，但在这种情况下，它是一个32位的值。话是处理器的话，这是典型的现代的说法32位。然而，魔兽争霸2是很久以前写的，运行在16位机器。肖恩在评论中指出的，字是16位，在这种情况下。

要回答这个问题在注释：

16多头= 16 * 32位= 512位= 64个字节。

110个字= 110 * 16位= 1760比特= 220字节。

I'm trying to read PUD file format, that belong to the warcraft 2 game map.

In the explanation of file structure, there is small phrases I don't understand it.

What is this mean (16 longs, 110 words) ?

Here is an example

16 longs -------> Units and buildings allowed. (16 players)

        x0000000000000000000000000000000        bit31: unused

Is this mean 16 longs = 16*4Bytes = 64 or 16*32Bits = 512 or other.
Also the same thing with 110 words.

解决方案

They're referring to C types on a particular architecture. In C, long is a type of variable. Its size varies as a function of the compiler, but in this case it's a 32-bit value. Words are processor words, which are typically 32 bits in modern parlance. However, Warcraft 2 was written a long time ago and runs on 16-bit machines. As Sean pointed out in a comment, words are 16 bits in this context.

To answer the question in the comment:

16 longs = 16 * 32 bits = 512 bits = 64 bytes.

110 words = 110 * 16 bits = 1760 bits = 220 bytes.
