我搜索了SO并用Google搜索，但我没有得到它们的含义。 他们和他们的目的是什么？ 他们什么时候用？ 我想也许在现代编程和我这一代人中看到它们已经太迟了。

什么是棉绒 – 来自维基百科
在计算机编程中，lint是一个Unix实用程序，它在C语言源代码中标记一些可疑和非可移植的构造（可能是bug）; 通常，lint或linter是标记用任何计算机语言编写的软件中可疑用法的任何工具。 类似lint的行为有时适用于标记可疑语言使用的过程。 类似于Lint的工具通常执行源代码的静态分析。
作为术语的Lint也可以更广泛地指代语法上的差异，特别是在JavaScript和Python等解释语言中。 例如，现代lint检查器通常用于查找与某些样式指南不对应的代码。 由于这些语言缺少编译阶段，在执行之前显示错误列表，因此它们也可以用作常见错误的简单调试程序（将语法差异显示为错误）或难以找到错误，例如heisenbugs（将可疑代码引起注意“可能的错误”）。

描述
/*NOTREACHED*/ Suppresses comments about unreachable code. /*VARARGSNumber*/ Suppresses checking the following old style function declaration for varying numbers of arguments, but does check the data type of the first Number arguments. If you do not include a value for Number, the lint command checks no arguments (Number=0). The ANSI function prototypes should use the ellipsis to indicate unspecified parameters rather than this comment mechanism. /*ARGSUSED*/ Suppresses warnings about function parameters not used within the function definition. /*LINTLIBRARY*/ If you place this comment at the beginning of a file, the lint command does not identify unused functions and function parameters in the file. This is used when running the lint command on libraries. /*NOTUSED*/ Suppresses warnings about unused external symbols, functions and function parameters in the file beginning at its point of occurrence. This is a superset of the /*LINTLIBRARY*/ comment directive, but applies also to external symbols. It is useful for suppressing warnings about unused function prototypes and other external object declarations. /*NOTDEFINED*/ Suppresses warnings about used, but undefined external symbols and functions in the file beginning at its point of occurrence. /*LINTSTDLIB*/ Permits a standard prototype-checking library to be formed from header files by making function prototype declarations appear as function definitions. This directive implicitly activates both the /*NOTUSED*/ and /*LINTLIBRARY*/ comment directives to reduce warning noise levels.
也许其他工具也可以使用它们。
