问题描述
struct stat * stats IF_LINT（= 0）;
我不知道为什么IF_LINT（= 0）是否需要？
源代码是Linux上的df程序的df.c coreutils-5.2.1 \ coreutils-5.2.1 \ src
谢谢！
struct stat *stats IF_LINT (= 0);
I don''t know why "IF_LINT (= 0)" is needed ?
Source is df.c of df program on Linux coreutils-5.2.1\coreutils-5.2.1\src
Thanks!
推荐答案
语法错误，需要诊断消息的约束违规。
Syntax error, constraint violation that requires a diagnostic message.
然后问一些更相关的新闻组。 comp.lang.c讨论ANSI / ISO
C.
ask some more relevant newsgroup then. comp.lang.c discusses ANSI/ISO
C.
IF_LINT似乎是一个类似宏的函数。
您的问题的答案是：什么是IF_LINT？
我的第一个猜测是，在某种情况下，
或许如果使用lint，
该对象在声明后初始化。

IF_LINT appears to be a function like macro.
The answer to your question is: "What is IF_LINT?"
My first guess is that under a certain circumstance,
perhaps if lint is being used,
the object is initialized upon declaration.

即使前面有一个类似函数的宏的合适定义
命名为IF_LINT（）？这是一个非常普遍的惯例，
all-caps中的标识符通常是宏，所以你至少应该考虑
。
Even if preceeded by a suitable definition of a function-like macro
named IF_LINT()? It is a very common convention that identifiers in
all-caps are generally macros, so that''s something you should at least
have thought about.
