ANSI C是否具有PATHMAX或MAX_PATH之类的东西？ [英] Does ANSI C have something like PATHMAX or MAX_PATH?

问题描述

嗨！


我查看了常见问题解答，但一无所获。 :-)


看来这种宏依赖于平台，不是吗？


谢谢。

Hi!

I have looked through the FAQ but found nothing about it. :-)

It seems that this kind of macro is platform dependent, doesn''t it?

Thank you.

标准宏FILENAME_MAX应该是大到足以指定一个

字符串，它将保存最长的名称，可用于打开

文件。宏是标准的，它的_value_将根据

平台改变，就像UINT_MAX或DBL_EPSILON一样。这就是为什么它们是

宏而不是指定的文字值。

The standard macro FILENAME_MAX should be large enough to specify a
string which will hold the longest name which can be used to open a
file. The macro is standard, it''s _value_ will change according to
platform, just as UINT_MAX or DBL_EPSILON will. That''s why they are
macros instead of specified literal values.

所有标准库宏定义都是取决于平台。

All standard library macro definitions are platform dependant.

PATH_MAX可能就是你的'想到了。我不记得那个

标准定义了它，但它不是ANSI C.如果跨平台也不会是

特定值这就是你所说的平台

依赖。

PATH_MAX is probably what you''re thinking of. I don''t recall which
standard defines it but it isn''t ANSI C. It''s also not going to be a
specific value across platforms if that''s what you mean by "platform
dependant".
