const typeof(((type *)0)->member)*__mptr = (ptr); \ (type *)((char *)__mptr - offsetof(type, member)); }) 首先看下三个参数, ptr是成员变量的指针, type是指结构体的类型, member是成员变量的名字。 container_of宏的作用是通过结构体内某个成员变量的地址和该变量名,以及...
#defineIOFFSETOF(TYPE, MEMBER) ((size_t) &((TYPE *)0)->MEMBER) 1.(TYPE*)0 将0强转为TYPE类型的指针,此时0作为一个匿名结构体的的起始地址。 2.(TYPE*)0->MEMBER 指向结构体中的MEMBER成员。 3.&((TYPE*)0->MEMBER) 获取MEMBER成员在结构体的地址,因为起始为0,所以获取的地址为相对偏移地址。
((type *)((char *)(ptr)-(unsigned long)(&((type *)0)->member))) 其中,ptr为指向该结构体成员的指针,type为该结构的类型,member为该结构成员的名称。 理解: &((type *)0)->member的目的是为了获得上图中问号表示的范围的大小。这段代码等价于: type * p = (type *)0; //便于获得某个结构...

简介:offsetof宏的使用、模拟实现及 (size_t)&(((struct_type*)0)->mem_name)的解释 宏原型:offsetof(type,member) 作用:返回数据结构或联合体类型中成员的偏移量,以字节为单位 返回值:size_t类型的无符号整数 使用案例: #include <stdio.h>#include <stddef.h>struct foo {char a;char b[10];char c...

did this one time as it killed the member of your party that did it. Which did not hurt me as I made it through most of the game no problem. I loved the fact you could send a character into something called 'secret training' and level them up while one is away. There are still ...
Type I phosphatidylinositol 4-phosphate (PtdIns(4)P) 5-kinases (PIP5K) catalyze the synthesis of phosphatidylinositol 4,5-bisphosphate, an essential lipid molecule in various cellular processes. Here, we report the cloning of the third member (PIP5Kγ) and the characterization of members of the...
