问题描述
根据最近的clc ++火焰战，半无处不在但又不是ANSI
strdup（）函数实际上违反了C标准，因为它是非法的
命名。如果这是真的，它违反了哪些标准命名规则？

According to a recent c.l.c++ flame war, the semi-ubiquitous-but-not-ANSI
strdup() function actually violates the C standard, because it is illegally
named. If this is true, what standard naming rule(s) does it violate?

根据最近的clc ++火焰战，
我不会称之为火焰战争，但是有些人不同意，而且有些人在学习。 :-)

。
是的，它违反了保留的名称约束。
如果这是真的，它违反了哪些标准命名规则？
According to a recent c.l.c++ flame war,
I wouldn''t call that a ''flame war'', but a few folks
disagreeing, and some learning. :-)

Yes, it violates a reserved name constraint.
If this is true, what standard naming rule(s) does it violate?

所以，从本质上讲，这就是说标准可能会选择
指定一个标准的strdup（）函数？想想看，因为strdup（）是广泛使用的b $ b，为什么它不是标准的？它不是特定于实现的（例如，
，htonl等）...

So, in essence, this is saying that at some point the Standard may choose to
specify a standard strdup() function? Come to think of it, since strdup() is
widely used, why isn''t it standard? It isn''t implementation-specific (like,
say, htonl and such)...

Sections 7.26.10 and 7.26.11 of the C99 standard says that in
the future, functions that begin with "str" might be added to
the <stdlib.h> and <string.h> headers.
The rationale for 7.26 ends with "Users are advised that failure
to take heed of the points mentioned herein is considered
undesirable for a conforming program".
