USHORT is a macro which is not part of the official C++ language (it's probably defined or typedef'ed somewhere). unsigned short is an official type defined by the C++ language as an integer that can at least hold numbers between 0 and 65535.
USHORT 是一个宏，它不是官方 C++ 语言的一部分（它可能在某处定义或类型化）。unsigned short 是 C++ 语言定义的一种官方类型，它是一个整数，它至少可以容纳 0 到 65535 之间的数字。
Use unsigned short and your code will be portable - don't use USHORT unless you company's coding standard requires it.
使用 unsigned short 并且您的代码将是可移植的 - 除非您公司的编码标准要求，否则不要使用 USHORT。

unsigned shortis a standard C++expression and USHORT is not. The precise definition can be found in the Wikipedia article Integer (computer science).
unsigned short是标准的C++表达式，而 USHORT 不是。精确的定义可以在维基百科文章整数（计算机科学）中找到。
Sometimes, we typedef unsigned short USHORT in the header. Then USHORT can be used as well as unsigned short.
有时，我们在标题中键入def unsigned short USHORT。然后可以使用 USHORT 以及 unsigned short。
