推荐答案

使用 uname() POSIX/BSD库函数.你声明一个 struct utsname 类型的变量并传入它的地址.结构的 release 字段将包含一个带有Darwin版本号的C字符串，例如"16.3.0".如果要将各个组件作为整数，则必须自己解析.

Use the uname() POSIX/BSD library function. You declare a variable of type struct utsname and pass in its address. The release field of the struct will contain a C string with the Darwin version number, such as "16.3.0". If you want the individual components as integers, you'll have to parse it yourself.
