使用GLuint而不是unsigned int的优点是什么？ [英] What's the advantage of using GLuint instead of unsigned int?

问题描述

我喜欢更标准的可能，所以为什么我应该约束我的类定义它的成员作为OpenGL类型，当我可以使用原始类型？是否有任何优势？

I like to be more standard as possible, so why should I "constrain" my classes defining it's members as OpenGL types when I can use primitive types? Is there any advantage?

推荐答案

类型unsigned int根据您构建的平台而有不同的大小。我期望这通常是32位，但它可以是16或64（或其他 - 取决于平台）。

The type "unsigned int" has a different size depending on the platform you're building on. I expect this to normally be 32 bits, however it could be 16 or 64 (or something else -- depending on the platform).

库特定类型通常创建根据平台特定的规则被typedef。这允许通用应用程序使用正确的类型，而不必知道它将被构建的平台。相反，平台特定的知识被限制到单个公共头文件。

Library-specific types are often created to be typedef'd according to platform-specific rules. This allows a generic application to use the right type without having to be aware of the platform it will be built for. Instead, the platform-specific knowledge is constrained to a single common header file.
