FuncRet FuncName##__VA( ExtraDecl FmtType Fmt, ... )
使用VARARG_DECL宏在头文件中，定义了0~28个不同参数类型的appThrowf函数(注：1~28用函数模板来定义)，appThrowf通过CheckVA进行类型检查后，最后调用appThrowf__VA
VARARG_DECL( void __cdecl, static void, VARARG_NONE, appThrowf, VARARG_NONE, const TCHAR*, VARARG_NONE, VARARG_NONE );
注：像printf函数一样，不定参数函数必须声明为__cdecl调用，由调用者来负责栈的清理
使用VARARG_BODY宏在cpp文件中实现appThrowf__VA函数：
VARARG_BODY( void VARARGS, appThrowf, const TCHAR*, VARARG_NONE )
{
static TCHAR TempStr[];
va_list ap;
va_start(ap,Fmt);
_vsntprintf_s(TempStr,,,Fmt,ap);
va_end(ap);
throw( TempStr );
}
注：可变长参数函数说明，如下Add为一个可变长参数函数
int Add(int count, ...)
{
int result = ;
va_list vl;// 定义char*指针v1 va_list为char* <== typedef char* va_list) va_start(vl, count); // 初始化char*指针v1到可变参数的起始处 第二个参数一定要是...之前的那个参数，用于定位可变参数的起始地址 for (int i=; i<count; i++)
{
result += va_arg(vl, int);
} va_end(vl); // 将char*指针v1设置为0 return result;
} int sum = Add(, , , ); // sum=60
va_list是一个char*类型 typedef char* va_list
va_start、va_arg、va_end是三个宏，定义如下：
#define _INTSIZEOF(n) ((sizeof(n)+sizeof(int)-1)&~(sizeof(int) - 1) ) #define va_start(ap,v) ( ap = (va_list)&v + _INTSIZEOF(v) ) //v为...之前的那个参数，用于定位可变参数的起始地址
#define va_arg(ap,t) ( *(t *)((ap += _INTSIZEOF(t)) - _INTSIZEOF(t)) ) //下一个参数地址
#define va_end(ap) ( ap = (va_list)0 )
在代码中的使用appThrowf：
INT AppendIndex = , ImportIndex = ;
const TCHAR* szName = TEXT("Frozen");
appThrowf(TEXT("Script patch attempting to add new import (%i) which matches an existing import (%i): %s"),
AppendIndex, ImportIndex, szName);
