很多编译器有“使结构体字，双字或四字对齐”的选项。但是，还是需要改善结构体成员的对齐，有些编译器可能分配给结构体成员空间的顺序与他们声明的不同。但是，有些编译器并不提供这些功能，或者效果不好。所以，要在付出最少代价的情况下实现最好的结构体和结构体成员对齐，建议采取下列方法：-Many compiler structure word, double-or quadword aligned " option. But still need to improve the alignment of the structure members, some compilers may be assigned to a different order of the space of the structure members declared their. However, some compilers do not offer these features, or ineffective. To pay at least the consideration of the case to achieve the best structure and structure members aligned, it is recommended to take the following methods:
