编译器错误 C2496

“identifier”:“selectany”只能应用到有外部链接的数据项

selectany 属性只能应用于外部可见数据项和全局数据项。

以下示例生成 C2496：

// C2496.cpp
// compile with: /c
__declspec(selectany) int x1 = 1;
const __declspec(selectany) int x2 = 2;   // C2496
static __declspec(selectany) int x6 = 6;   // C2496

extern const __declspec(selectany) int x3 = 3;

__declspec(selectany) int x4;

// dynamic initialization of x5
int f();
__declspec(selectany) int x5 = f();

extern const int x7;
// OK - redeclaration of x7 that is extern
const __declspec(selectany) int x7 = 7;
