如何在使用 g++ 编译器时使用 c 样式初始化结构? [英] How to initialize a struct using the c style while using the g++ compiler?
问题描述
一般来说,为了在c中初始化一个struct
,我们只能指定部分字段.如下图:
Generally, in order to initialize a struct
in c, we could only specify part of the fields. Like below:
static struct fuse_operations hello_oper = {
.getattr = hello_getattr,
.readdir = hello_readdir,
.open = hello_open,
.read = hello_read,
};
但是,在 C++ 中,我们应该在不命名字段的情况下初始化 struct
中的变量.现在,如果我想在使用 g++ 编译器的同时使用 c 样式初始化一个 struct
怎么办?PS:我需要这样做的原因是 struct fuse_operations
中的字段太多.
However, in C++, we should initialize the variables in the struct
without naming the fields.
Now, what if I would like to initialize a struct
using the c style while using the g++ compiler, how to accomplish this? PS: the reason I need to do this is that the struct fuse_operations
has too many fields in it.
推荐答案
不幸的是,即使是 C++ 标准的 C++11 版本 缺少 C99 的指定初始化器功能.
Unfortunately, even the C++11 version of the C++ standard lacks the designated initializers feature of C99.
