lstrcmp: 按系统语言设置 对字符串排序

lstrcmp: 按系统语言设置 对字符串排序

The lstrcmp function compares two strings by checking the first characters against each other, the second characters against each other, and so on until it finds an inequality or reaches the ends of the strings.

Note that the lpString1 and lpString2 parameters must be null terminated, otherwise the string comparison can be incorrect.

The function returns the difference of the values of the first unequal characters it encounters. For example, lstrcmp determines that "abcz" is greater than "abcdefg" and returns the difference of z and d.

The language (user locale) selected by the user at setup time, or through Control Panel, determines which string is greater (or whether the strings are the same). If no language (user locale) is selected, the system performs the comparison by using default values.

With a double-byte character set (DBCS) version of the system, this function can compare two DBCS strings.

The lstrcmp function uses a word sort, rather than a string sort. A word sort treats hyphens and apostrophes differently than it treats other symbols that are not alphanumeric, in order to ensure that words such as "coop" and "co-op" stay together within a sorted list. For a detailed discussion of word sorts and string sorts, see the Remarks section for the CompareString function.
