如何克服mmsystem.h引发的错误

Question

我无法摆脱这些简单的错误,但是如果有人能够从这些错误中解脱出来,那么它就会非常充实.我包括了windows.h和一些其他必要的标题,但无法摆脱它.

错误片段:

error C2146: syntax error : missing ';' before identifier 'MMVERSION' 
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int error C4430: missing type specifier - int assumed. Note: C++ does not support default-int error C2143: syntax error : missing ';' before '*' 
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int error C2146: syntax error : missing ';' before identifier 'ms' 
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

为了扩大在安东的回答是:WINDOWS.H #defineš UINT是unsigned int.这是一个C宏定义,而不是typedef.如果你#include windows.h在#include mmsystem.h他之前他指出的那一行将被解读为:

typedef unsigned int MMVERSION;

但是,如果你以错误的方式执行它,那么UINT将扩展为空,并且该行将变为:

typedef MMVERSION;

这不是有效的C++,你会得到一个解析错误.这正是你得到的.
