push就是将当前正在使用的对齐系数n1保存到内部栈顶部，这样当再次设置新的对齐系数n2时，就不会覆盖掉n1。pop是将内部栈顶部的n1弹出来覆盖当前的对齐系数n2，使得当前对齐系数编程n1。注意，#pragma pack()指令总是恢复编译器默认的对齐系数。举例说明：#pragma pack(n1)...#pragma pack(push)#pragma pack(n2)...

If you specify the #pragma GCC visibility pop directive without the corresponding #pragma GCC visibility push directive, the compiler issues a warning message. Entity visibility attributes describe whether and how an entity defined in one module can be referenced or used in other modules. Visibility...
