＆是什么QUOT;防爆＆QUOT;在Windows API函数的名字代表什么？ [英] What does "Ex" stand for in Windows API function names?

问题描述

在windows API和在那里我看到了多个入口点方法的各种其他图书馆我已经注意到了利用方案如MyApiCall和MyApiCallEx防爆缩写。

我的假设是，这代表了延期或额外可能有人请证实？

My assumption is that this stands for Extension or Extra could someone please confirm?

为什么前被选为而不是MyApiCall2或类似的也将是AP preciated任何历史。

Any history on why Ex was chosen rather then MyApiCall2 or similar would also be appreciated.

推荐答案

我是IM pression它主张延长，在该特定库更详细的接口下。

I was under the impression it stood for extended, as in a more detailed interface for that particular library.

例如，的CreateFile用4参数是典型的版本和CreateFileEx用17版本提供更多的控制和更精细的细节在如何打开该文件，所发生的问题，如果它不存在，等等，并且因此延长。

For example, CreateFile with 4 parameters is the typical version and CreateFileEx with 17 is the version offering more control and finer detail over how the file is opened, what occurs if it doesn't exist, etc, and is thus extended.
