os.Mkdir versus syscall.Mkdir, what is the difference in Golang?

问题

os.Mkdirsyscall.Mkdir在Golang中具有相同的API。

syscall.Mkdir:

func Mkdir(path string, mode uint32) (err error)

os.Mkdir:

func Mkdir(name string, perm FileMode) error

它们之间有什么区别?

英文:

os.Mkdir and syscall.Mkdir both have same API in Golang

syscall.Mkdir:

func Mkdir(path string, mode uint32) (err error)

os.Mkdir:

func Mkdir(name string, perm FileMode) error

What is the difference between them?

答案1

得分: 3

第一个是直接的系统调用,依赖于平台,可能更快/可以使用所有平台相关的位(例如Unix/Linux上的粘性位)。

后者是可移植的API,应该在每个平台上都能正常工作,注意第二个参数不再是匿名整数,而是一个受限制的类型。

英文:

The first one is the direct system call, platform dependent, probably faster/you can use all platform dependent bits (like sticky bit on Unix/Linux for instance)

The latter is the portable API which is supposed to work the same on every platform, note that second argument is no longer an anonymous integer but a constrained type.
