Binary source data must be a single-dimensioned array of unsigned char.

二进制源数据必须是一维的无符号字符数组。

If you need more, read the data in as a stream of unsigned char objects and do the math.

如果您需要更多功能，请将数据作为一个无符号字符对象流进行读取，然后进行匹配。

The unsigned char data type, and byte data type will yield incorrect results and act as though they are signed types i. e. type char.

无符号字符数据类型和二进制数据类型将产生错误的计算结果，会当成有符号的数据类型进行计算。

For example, if a function returns an unsigned char value but calculated a result of 256 or more (or -1 or less), errno would be set to ERANGE and the function would return some irrelevant value.

例如，如果函数返回unsigned char值，但计算的结果为256或更多(或者是- 1或更少)，则errno将被设置为ERANGE且函数会返回一些不相关的值。
