1.FIELD_SIZEOF获取成员大小 FIELD_SIZEOF用来获取成员大小。它需要两个参数,第一个指定结构体的类型,第二个则指明成员的名字。 1include/linux/kernel.h2#defineFIELD_SIZEOF(t, f) (sizeof(((t*)0)->f)) 它通过对0指针灵活运用,是对sizeof的一种变相扩展。 2.ARRAY_SIZE获取数组维数 ARRAY_SIZE用来获...

The compiler may also allocate 2 16-bit numbers (one for each 11-bit value) and then decide to piggyback the 2-bit value into one of these 16-bit integers. This gives a total size of 6. The compiler may decide that the 2-bit field should not be piggybacked, thereby consuming 5 byte...
kernel FIELD_SIZEOF宏 -- NULL地址不访问不出错 Linux kernel的宏: #define FIELD_SIZEOF(t, f) (sizeof(((t*)0)->f)) 为什么不会segment fault?因为没有访问那个f。一旦有访问,就会segment fault,比如: #include <stdio.h> struct a { int f;...

sizeof(MyStruct)为2,而Marshal.SizeOf(typeof(MyStruct))结果则为1。这是因为在.NET中char总是Unicode,而缺省情况下char会被Marshal成8位的Ansi字符,因此结果不同。 反之,如果我们指定这个char被Marshal成short值(也就是UTF16),如下: 1:[StructLayout(LayoutKind.Sequential)] ...
