②push:可选参数;将当前指定的packing alignment数值进行压栈操作,这里的栈是the internal compiler stack,同时设置当前的packing alignment为n;如果n没有指定,则将当前的packing alignment数值压栈; ③pop:可选参数;从internal compiler stack中删除最顶端的record;如果没有指定n,则当前栈顶record即为新的packing align...
使用Visual Studio选项(以Visual Studio 2008为例) Projects-Properties-Configuration Properties-C/C++-Code generation-Struct Member Alignment, 如果没有修改过,则默认值是Default,即8字节对齐。 如何修改结构体的对齐值 使用预处理指令 #pragma pack(num) num是结构体的对齐值,比如下面的例子按四个字节对齐。 #pr...
Okay, it's quite like that, but not the same. Of course, the compiler adds padding and tries to align the data members. So for the above structure, the data alignment looks like below, Above is the alignment of the structureA, and that's why thesize of the struct is 32 Bytes. Als...
Default- Default alignment settings. Security Check The Security Check helps detect stack-buffer over-runs, a common attempted attack upon a program's security. Choices Disable Security Check- Disable Security Check. Sets/GS-. Enable Security Check- Enable Security Check. Sets/GS. ...
cstruct analyzes the structure and can either extract the bytes from it, or pack bytes into the structure. Various byte alignment and byte ordering options are supported. Since I've written this, I've found it to be more useful that I thought, as I regularly deal with recorded data and ...
alignment属性规定变量或者结构体成员的最小对齐格式,以字节为单位。 struct qib_user_info { __u32 spu_userversion; __u64 spu_base_info; } __aligned(8); 在这个例子中,编译器以8字节对齐的方式来分配qib_user_info这个数据结构。 packed属性可以使变量或者结构体成员使用最小的对齐方式,对变量是以字节...
